Chevy - Malibu :: 2003 V6 3.1 - Coolant Loss / Loud Knock / Loss Of Power And Misfire?
I have a 2003 Chevy Malibu, V6, 3.1, auto, 140k miles. Car started out with code 0420 with no noticeable symptoms, but then added code 0303 (miss fire cyl #3) with loud knock (mostly after warmup) and loss of power under load. Now internal loss of coolant (no puddles or external drips). Changed plugs and wires - no change - all plugs looked good with no sign of contamination. Questions - if this is a valve/piston/lifter problem (which would explain the knock, miss-fire and loss of power), why would I get the loss in coolant? If the loss of coolant is fouling plug #3 (which would explain the coolant loss, miss fire and loss of power), could that give me the loud knocking? I don't see how a valve/piston/lifter issue would cause a leak in coolant but I also don't see how a coolant leak into cyl #3 would give me such a loud knock. Do I have two different problems? If it is a leak into cyl #3, is there any way to tell if it is the intake manifold gasket (which leaked before and was replaced five-six years ago and which I could do again if I had to) or a blown head gasket (which I don't think I could fix or afford to get fixed)? Engine will occasionally get hot (but not overheat).

My son has a 2000 S10 that runs alright as long as he only drives it about 20 miles one way, the problem seems to occur after he goes on longer trips, closer to a 45 or 60 mile drive, and it seems to happen when he comes to a stop, at a red light, or stop sign, the other day I drove it to my daughters house which is a 45 minute drive, we stopped several times, before I made it to her house, just when I though we were going to make it with no problems, I come to a stop at a red light, when I start to pull off the truck becomes so sluggish, that the truck motor can barely keep running, when I let off of the gas it seemed to pick up power, but every time I pressed the gas it would bog back down, I barely made it across the intersection, trying to get to a parking lot, when the power is just to low to pull any more, so I leave it running, but put it in park, so my wife can get behind the wheel, thinking, that if she presses the gas, while I push it, we can make it to the parking lot.
Well as soon as I got behind the truck, I tell her to put it in gear, and press the gas, while I push, well the truck takes off and she drives it in the parking lot, I walk on up to were she had parked, there was a burned rubbery, or oil smell coming from the truck, not should which, I’m checking everything out, when I take the power steering cap off, it releases air out of it, like there was press build up in it, after that I crank the truck back up, and drive it to my daughters house, and back home with no more problems, the check engine light came on when this happen, but has now gone back out, now, like nothing is wrong, what could cause this? I have check everything maintenance wise and everything is in good working order it doesn't run hot, it has the right oil pressure and amount of oil in it, has the right amount of transmission fluid and power steering fluid, I took it to a mechanic, but he said he didn't find anything wrong with it, and told me to just drive it, till what ever was causing this tore up.
Chevrolet - Camaro :: Loud Backfire And Loss Of Power
I own a 1988 Camaro Iroc-Z with a 5.7 350 TPI motor. I was driving the car onto I-95 at a speed of 65 when I heard a loud boom under my car, and pulled over to see what had happened. I couldn't see what happened, so I drove the car slowly to a friends garage to find the exhaust pipe from the converter back to the muffler had split and blew apart. I took my car to another shop to repair the pipe, but when I left the shop after the repair, I accellerated to about 40 mile per hour, I get another loud backfire and loss of power. The pipe is still intact, but I cannot figure out what is causing the backfire. My friend from the first garage says it is a failing fuel pump. I never heard of such a thing to be honest.I am at a loss and I have to correct the issue soon, as this is my only car to drive.
View 4 RepliesGolf/GTI VII :: Loss Of Power Especially After 2nd Gear
About 3 weeks ago I purchased my MK7 GTI SE w/ DSG. About a week ago, I started noticing a very slight rasp around 3.5k and up under heavy WOT. Note the sound was very subtle in the cabin and unsure what it sounded like outside. This past weekend, I started noticing a loss in power, especially after 2nd gear. A strange sound under throttle--almost sounds like a supercharger winding down (hollow with a slight whine)--when giving a good bit of gas around 2.5k and up occurs. At first I though it was road noise from my neighborhoods new roads since the sound only occurs on new roads, but realized that noise never occurred the first few weeks I had the car. No CEL.
I took it to the dealership on a rainy day, so they couldn't see the loss of power with the car breaking loose, but they didn't find anything. I'm bringing it back this Friday to see what they can find. I talked with one of the service guys today and they think it may be a drivetrain problem. Supposedly no loose hoses and is holding boost normally. Any leads to what it may be??
Chevrolet - Montecarlo :: Loss Of Power / Surge Or Lunge Forward When Accelerating
2002 Chevy Monte Carlo SS 6cyl 100,000 miles
Symptom, loss of horse power (from a stop and going uphill), surge or lunge forward when accelerating (misfire?), rough idle (occasional knock). Maintenance, regularly change all filters and fluids, recently had the m.a.f cleaned and changed air filter, spark plugs and wires, oil.
There have been times in the past year or so when the car would crank but not start. Especially when the car was hot. Wait a couple minutes and it would start. Also a couple of times the car would shake fairly hard when started, get up to speed and it was fine.
I have had people tell me anything from a clogged catalytic converter to bad fuel injectors or fuel pump.
Scanned the car last week. No codes showed up. Never had a Check Engine Light.
I forgot to mention that every once and a while the car will jerk when accelerating. I have a coworker who said his truck started to jerk forward and later would not start at all. Our mechanic said it was the fuel pump. I I will see what that does for him.
Chevrolet - Silverado :: 2002 Power Loss And Service Engine Soon Light Blink
Driving while in 4x4 HI up a hill the truck started to slip. I stopped, shifted to neutral, and engaged 4x4 Low. I shifted back to drive and started moving up the hill. The engine started to lose power and the "Service Engine Soon" light began to blink. I put the truck in park. As I let it run a little bit, the engine started to shake as if something was very imbalanced. I went to check under the hood, and confirmed that it was shaking quite noticeably. There was no grinding or clattering of any kind though.
I turned the truck off for a bit, and then restarted. There was no light or shaking upon starting up; but as soon as I put it in gear and started driving I could tell it was losing power, the light came back on, and the shaking ensued. This occurred in 2wd, and both 4wd lo and hi. I parked it at a neighbors place and there it sits for now.
I plan to try and get the codes read. My other vehicles can't make it through the snow we have right now, but it is suppose to get warm later today and might melt enough for me to get one out. I also live out in the country, so the nearest auto parts place is about 20 miles. Same with a dealership service shop. I'm hoping I can buy and return a code reader from an auto parts store to assess if this is something I can diagnose myself or not.
It is the 6.0l gas engine with the 4sp automatic transmission. The truck also has about 107,000 miles.
Chevrolet - 1500 :: 2002 - Power Steering Loss When Stopping / Approaching To Stop
The vehicle: 2002 Chevy Silverado 1500 w/ Z71.
The problem: Steerage issue. No problem exhibited while driving. However, at stop or very slow there is a loss of power steering but only when turning the wheels right. There is also an audible sound when turning to the right. Kind of a whooshing or air expulsion?
Chevrolet - 1500 :: Slight Rough Idle / Loss Of Power - Vacuum Leak
I have a misfire in the 6 cylinder on my 98 Chevy c1500 5.7l 350 v8 2wd. I changed the spark plugs and wires, cap and rotor, and changed the spider injector i put the spider injector in from another engine I had. After doing all this the code still comes up. The truck runs fine and except it idles slight rough not bad at all and now it says I have a vacuum leak and while I'm driving you can feel the loss of power. I tried all the ways to do it like on YouTube. What is wrong with my truck?
View 10 RepliesChevrolet - Suburban :: 1994 - Slower When Accelerating Cold Or Warm / Power Loss
I have a 94 Chevy Suburban C1500 with a 5.7L, 350 Engine. It has 235,000 miles on it. I purchased it about 4 years ago with 191,000 miles in very good condition and obviously well maintained. I have continued to maintain it well.
For the past few months it has begun to start a little slower that before and when accelerating cold or warm there is a spot where it looses power. It doesn't sputter or die it just looses power. I can press the accelerator farther and it will come back to life and do fine. After a 20 -30 minute drive if I park for a while, 20 - 30 minutes, when I start it up it dies. The only way to keep it running is to give it the gas and smooth it out at about 1500 rpm for 10 - 15 seconds. Then I can drive it with no problem most of the time though it still has the dead spot on acceleration.
There is a good spray pattern from the throttle body injectors. Plugs and wires are relatively new and plugs look good (AC Delco Rapidfire Platinum). When I turn on the ignition without going to start, the fuel pump builds pressure for 4 - 6 seconds. I haven't checked the fuel pressure yet and am considering investing in the rig to do so. I recently replaced the fuel filter but that didn't work.
The check engine light has not come on but many of the lights in the cluster are burned out and I haven't felt like going to the trouble to fix that so it is possible that the check engine bulb is bad.
Chevrolet - Cavalier :: 2001 - Loss Of Electrical Power Causing Lights To Dim / Fan To Slow
About 2 months ago, I needed to test my engine cooling fan motor. Was using two lead test wires with alligator clips and stupidly connected the battery ends first and then the wind blew the other connection ends together creating a spark. That may or may not have anything to do with what has happened since then. About 3 days after that, I started to notice that my lights were dimming and ac fan motor was slowing when the engine was under load as in 1st or 2nd gear or going uphill.
After about a week, the ALT/BAT light came on and I replaced my alternator. The problem with that was that getting the belt back on the new ALT nearly killed me and I got several pretty bad injuries and ended up having to get it done. The old alternator tested bad so I figured my problem was solved. But ever since then, I am still getting the same problem - a voltage drop or loss of electrical power causing the lights to dim and the fan to slow - except this time is doesn't happen under load - it happens while driving and just after I have come to a stop at a light or stop sign. I have had the battery and alternator tested several times and they always show up as being fine.
I checked all the cables and connections and changed the positive battery cable bolt. I get no codes thrown. I cant just take the alternator out and change it because of what I went through with the last one - not to mention it tests OK so I can't use the warranty as long as that is the case anyway. So I am left with this troubling, annoying problem and don't know what the cause or solution is. I am guessing the list of options has to have the alternator, battery, connections, belt (though I have no sounds or evidence there is a problem with the belt - I suppose if the tensioner was damaged with the belt fiasco that it might cause such a problem). What to do? It is the biggest problem at night because my headlights are affected.

Chevrolet - Blazer :: 1998 / V6 - Long Turnover Start / Really Rough Idle And Loss Of Power
What would cause my truck to have a long turnover start, a really rough idle, and a loss of power after idling at a stop light for about a minute?
This problem gets worse as the truck warms up. It feels as if I'm not getting power from all 6 cylinders but this goes away after about 20 feet of acceleration. The truck has never not started. It just has to turn over for about 5 to 10 seconds before it fires up. I changed the spark plugs and wires thinking it was that and then i tried the fuel filter and it wasn't that either.
Malibu - Chevrolet :: 1998 - Power Steering Fail Causing A Total Loss Of Fluid
I recently had the high and low pressure tubes on my power steering fail causing a total loss of fluid. After about a week of living with manual steering, I brought it in and had the tubing replaced. Everything worked fine, though the steering felt a bit sloppy to me. Today, on my way home from a 100 mile trip, the car decided that turning left just wasn't something it wanted to do.
So to turn left, I would have to back up and turn the wheels to the right. Not exactly an efficient way to drive in traffic. Do I try to get the car back into my mechanics place to see if he can fix it for a reasonable amount, or should just bite the bullet and look for a newer car? BTW when I had brought the car in for the tubing replacement, they showed me where the bracket holding the strut on the left had begun to crack, probably from driving without the power steering. 1998 Malibu LS ....
Golf IV R32 :: Hard Acceleration In 3rd Gear / Momentary Loss In Power
Having problems where sometimes the car won't go into gear, other times it's fine? The problem started after some hard acceleration in 3rd, there was what felt like a momentary loss in power. I dipped the clutch as I thought a boost pipe had popped off, all was fine (still seeing boost when revved). After this it got progressively harder to get gears, finally resulting in not being able to get into gear at all.
I found I could get it into 1st with the engine off and could go up gears normally, but couldn't change down without stopping and turning the engine off. The clutch is working fine, the biting point is normal. The problem seams to come and go randomly, it will work fine for a while and then start playing up again. When working the gearbox feels normal, there is no grinding or wining noises. I can move between gears normally and do clutch less gear changes.
There is now a vibration which can be felt at 1000rpm when stationary. It feels like it coming from the engine/gearbox and seems like something is out of balance as it shakes the whole car. The car is on 91k, supercharged running 470hp & 370lb/ft (at flywheel) and is fitted with a Spec stage 3+ clutch and solid flywheel.
Ford 7.3L Power Stroke (1999-2003) :: E350 - Sudden Power Loss / Zero Power
I am still failing to appropriately diagnose the problem(s) with my '03 Ford E-350 7.3L Powerstroke. This van has only 69,000 miles on it. A week or two back (just a few days back in work time) it suddenly went from running perfectly smooth, clean and wonderful to this:
- Zero power. Putting the van in gear and flooring the engine causes lots more smoke not nearly any rev of the engine and just a crawl forward.
- Lots of smoke out the back exhaust, whitish. I cannot discern wether it smells like diesel or oil (because I'm ignorant here), but the smell is very strong.
- After warming up and idling ~ 15 min I check under the coolant cap and see no signs of bubbling or disruption (from opening the cap in the coolant tank).
- After warming up there are no warning lights visible on the dash, and I don't have a computer to read codes (if there are any to read).
- I replaced the turbo up-pipes which had a visible leak previously. This did not hurt the symptoms, though no more visual leaks under the dog house.
- I thought maybe I put gasoline instead of diesel in the truck, not so.
- To do the above test I had to use the fuel pump to get gas out the tank to test. I hijacked the fuel pump output and turned the car on a few times to get gas out to a tank. The pump seemed to work just fine.
This was all very sudden which is perplexing, and, in use, the van was previously an ambulette and in my few miles with it (maybe 200-300 only) use was extremely light for such an engine/van, just driving around doing errands. I am not sure if this is relevant (no one has suggested so, yet) but before all this happened I uninstalled the rear HVAC that came with the van when I bought it. The AC lines were sealed under the hood. The coolant line was returned at the doghouse (you can see this at the beginning of the video).
At the moment the van has no power to go anywhere. I have not yet checked the CPS or IPC sensors, and understand this might be the next route in standard troubleshooting?

Sonata I45 (YF - 2011+) :: Loss Of Power / Falling Out Of Gear - Brake Light Stays On
I recently (July 2016) bought a 2012 2.0T Limited with 14K miles. Got an awesome deal on it and really love the car. About two months ago the car had a total loss of power/boost. I took it into the dealer and they performed a wastegate actuator adjustment (something I will be doing on my own now if it becomes a problem again). Now at about 21k miles I'm having a different issue. Here is what's happening:
Accelerating from a stop the car feels as if it's falling out of gear intermittently. Once it happens and I press the gas more/floor it, the car doesn't respond. If I let off the gas and then press it again, the car will then start to accelerate again. On the highway cruising at 70ish, the same thing happens and it even oscillates with constant throttle like its down/up shifting. The ESC light came after a 20 mile highway trip of this oscillation. No CEL. When I got off the freeway, the navigation screen said there may be a problem and I should press the bluelink button.
When this is happening the cruise control either doesn't work at all or the "cruise" light will come on but I can't set a speed. Tonight I noticed in the rear view mirror that the brake light stays on or even flutters after I brake which corresponds to when the cruise is or isnt working as well as when the car intermittently falls out of gear/oscillates falling out of gear with constant throttle. If I notice the brake light is on without actually braking, I can take my foot and pull the brake pedal towards me which turns off the brake light and then the car seems to work correctly as well as the cruise control. The car is driveable but definitely something is wrong.
I should mention that I checked the voltage for the wastegate actuator and it is 3.97v which I believe is within tolerance. All of these issues with no CEL.
Toyota - Corolla :: While Shifting Into 4th Gear And Accelerate The RPMs Drop - Power Loss
I have an 05 corolla XRS. I just had a sport clutch put in about 1 year ago. Whenever I shift into 4th gear and accelerate, the RPMs drop about 500 and I lose power for about 3 seconds before it starts going back up. Other gears are acting normal. Best part is that I let my friend drive the car earlier and since he did it's been doing this.

View 16 RepliesFord Super Duty (1999-2016) :: 2000 F250 2wd V10 - Loss Of Passing Gear Power
When passing or going up small inclines on freeway, my F250 seems to make the shift to the passing gear but then almost a complete loss of power. Jerks around for a few seconds and finally provides enough power to at least get back to the original speed. (It feels kind of like the lurching, etc. I used to get when those stinking GM diesel injectors would act up in the 1990's.)
It also stays in first/second as I punch it while entering the freeway and doesn't want to make the shift. I can put it in neutral and race the engine, so I don't think it is an engine problem, unless the transmission is electronically controlled. I have a lot of computer dashboard gauge resets after falling to zero and sometimes have to set and release the parking brake to get the auto door locks and windows to work. (That started after a car break in where the door electronics were apparently pinched, but that was a couple of years ago.)
Does it sound like the transmission or electronics? In the old days replacing an automatic transmission filter seemed to fix a lot of transmission issues. Not an option now, but would I expect to see any results doing a transmission flush and fluid change? It's probably been about 60000 since I had that done. (157000 now).
