Silverado :: Truck Is Running Rough / Loss Of Engine Power?
why my truck is running rough the problem I am having is when you push the gas peddle more than a 1/4 of an inch it shudders and has no get up and go and also if say I'm doing 40 MPH and hit the gas you can hear the engine rev up but I will lose all power and actually lose speed I thought maybe the cats were bad and I changed the plugs for good measure but I can't seem to figure it out also I had the fuel pressure checked and its pulling pressure is great/

I own a 2004 Silverado 1500. Nearly every time I drive, I loose temperature control on the driver's side after about 15 minutes of running the engine. The passenger's side seems to be working fine. I'm not sure if it is a bad rheostat on the driver's side or a bigger issue.

I have a 1993 Chevy Silverado rwd automatic 350 5.7. It died on me on the way to work this morning. It slowly lost power and acceleration. The lights and radio all worked. When I tried to restart, it tried to start but then just cranked like it had no fuel or spark.
I had it towed home and checked the following things. I removed the fuel filter, it is clear. I verified that the fuel pump was working by turn the key to the on position while the filter was off. Good stream of fuel. I verified that there was fuel to the TBI. Good spray while cranking. I verified that there was spark by pulling a plug out, connecting to the wire and cranking the engine. Spark seemed weak but there was spark. The front plugs were dry, but the rear plugs, especially #8 was very wet. I verified the timing by pulling the #1 plug, removing the distributor cap and checked the rotor position. I bumped the engine to get the #1 piston to the top of the cylinder and the rotor was point directly at the #1 plug wire. The cap, rotor, plugs and wires are only 1 month old.
I also tried to check the ignition coil by disconnecting the coil wire from coil, and slid the boot back to expose the contact. I held it just of the coil while the engine was cranked, but did not actually see a spark at the coil. I did not hear any arcing. I pulled another plug and checked for spark. Again i had spark. Just seems weak to me. I am on my way to the auto parts store to get a new coil.
Porsche - 911 :: 1977 - Backfiring And Popping When Heated While Driving
My Porsche is backfiring & popping when it has heated up while driving. What could this be? I took it to a Porsche repair shop where the guy changed the Perma-Tune Box and replaced the coil and charge me over $1400.00 and the car is still doing the same thing. Could this be a tune up problem?

My 2003 6.0 truck lost most of its power. It has the SCT programmer. It used to run great it would roll coal really well then it slowly started to run worse. Now it runs really sluggish especially when its cold. IT takes forever to warm up. On the freeway when ur going a constant speed it bucks and jerks a lot. It won't roll coal anymore and just runs like crap. A mechanic said I had 3 bad injectors. But I don't believe it.
View 2 RepliesSanta FE SM (2001-06) :: Rough Running While Driving / 2 Of 4 Cylinders Lost
2001 Santa Fe with 2.4 engine auto FWD 198k miles. When it is started first in the day, the engine sounds good and shifts well. After a few minutes and also after stops, first gear works well but then the following gears do not work well almost as if the engine and the transmission quit talking to each other. Traveling at 60 mph starting up a medium hill, the car downshifted and could not pick a gear. Although I pushed the pedal harder, the car did not respond rather continued to slow down. It acts like I lose 2 of the 4 cylinders in all cases. I replaced the spark plugs and two of them had oil on top of the plugs and also all around the threads. I replaced both coils thinking that one of them was the issue but no change has been observed. I replaced the throttle position sensor; no performance change. I do not believe it is the transmission as I have not notice any clunking, or bad shifting when starting out. While coasting at 40 mph in neutral and my pedal pressed at a certain position, the rpm gauge fluctuated from 3k to 3.6k many times for the duration of 20 seconds.

More times than not now, when making a sharp left turn and sometimes a left turn in general, a loud popping/clanking/knocking noise comes from the rear of my truck. I can feel it in the steering when it's about to do it. The steering wheel will become stiff when turning left and when I straighten up it will pull to the right (just got the truck aligned so I don't think that's a problem). Rear left tire will spin like its struggling to spin. After all that I can make a hard turn right and "pop" everything will seem to go back to normal. 1999 Silverado Z71 5.3l ....
View 5 RepliesFord 7.3L Power Stroke (1999-2003) :: Loss Of Power / Rough Running
I have a 2001 ford 7.3l powerstroke diesel. When I first noticed the problem I was towing a trailer going up a grade and got into the throttle almost to the floor and noticed a loss of power and the service engine soon light flashing extremely rapidly a few times and never came back on. I made it home, still lacking power but not running rough. I drove the truck to work the next day and the truck was running rougher and loosing power. It ran great through lower RPM's but seemed to trip as soon as you gave it over half throttle. eventually the truck wouldn't run right at all and lacked complete power. It idled rough as well. My mechanic threw the computer on it and it said injector pressure reading too high or too low.
I was told to replace the IPR on the HPOP and I did. (I also replaced the fuel filter and changed the oil). After replacing the IPR it ran great, had full power! then it began to slowly die like it did before until it sounded like it was running off 4 cylinders again. I pulled the ipr out, cleaned it and changed the oil again. It seemed to clear it up for an hour and ran great but then began ran rough again. I also replaced the CPS sensor. I feel like its not getting enough fuel or something, im just wondering if it could be the ICP or the lift pump. There is no check engine light at all. Its just got me stumped because cleaning the IPR clears everything up.... temporarily.

Well, I was headed out from work this morning, on my way to fill up as I was a bit below 1/4 tank.
Truck was running good, like normal, until after 5-6 minutes, when it started running rough and had no power. Worried, I pulled off the side of the road. As I did so, it died, and wouldn't start again.
I whipped out my phone, pulled up TorquePro, and ran a code check. Nada. Well, it sounds to me like it's not getting fuel possibly, so I figure the best way to check, is to drain the fuel filter bowl, and crank it some, and check the bowl. No fuel in bowl.
Wifey came to pick me up with the can of diesel I keep for starting my forge (had 3 gal maybe?). Poured it in the tank, cranked it, no start. Still nothing in the bowl.
I'm taking her to work now, so she won't be late, then I'm headed back with a full can of diesel.
If that full can still won't get it, should I keep shuttling diesel cans, or should 8 gal or so be enough to get it back to the fuel pickup level? And if it's not fuel level, what else should I start checking on the side of the road?
Ford 7.3L Power Stroke (1999-2003) :: Rough Running / No Power After Just Driving A Block Or Two
I have had this happen twice now. Starts fine, idles fine, then either sitting or just driving a block or two it starts running very rough, no smoke that I remember seeing, and now no power. Barely makes it up a hill. The first time I thought is was related to the heavy rain the night before. I had the tow truck coming and decided to try it again, this was after a few hours sitting. Ran perfectly. The second time, no wetness/rain, pulled away from the house and in a block or two, same thing ... rough, no smoke, no power. Pulled back into driveway, turned off for a minute, restarted and ran fine. Ran perfect today. What is the best injector cleaner to use in the fuel?
View 3 RepliesFord 7.3L Power Stroke (1999-2003) :: 2002 F250 Idling / Running Rough And No Power
2002 F250 7.3L suddenly idling and running very rough, and doesn't have any power. Truck has been running perfect, it's my daily driver, and just put a couple hundred miles on it yesterday with no problems. I had been having some transmission issues when I tow heavy so I bought a new transmission yesterday. This morning I pulled the truck into my garage to change the transmission. Again truck ran fine, no signs of any issues before the trans swap. I changed out the transmission, which included unhooking the trans wiring harness from all the various sensors, and unbolting the starter.
I didn't mess with anything in the engine bay except for unhooking the batteries. I had also repaired the overdrive button wires, as they had been pinched in the steering column and the button wasn't working. When I got everything hooked back up I cranked it up to get the trans fluid flowing through the transmission, it started right up and idled good. I had it running for a few minutes and it was beginning to make a little more noise than usual. When I started to back out of the garage it was getting pretty rough, almost like it was running out of diesel. I put it in neutral and gave it some throttle and noticed I was getting white smoke out of the exhaust and could smell diesel pretty strong.
I checked my injector resistance at the valve covers and got around 4 ohms +/- on all of the injectors. I rechecked all of the clips and harness that I had messed with. I took a look at the ICP sensor and it has oil in the connector which I know can cause a rough running condition in some cases. It looks like it has had oil on it for a while. I unhooked the batteries again for about 20 minutes to try and reset anything that may have messed up. I checked a bunch of connections under the hood to see if anything was unhooked or loose.
I also cleaned up the connector on the ICP sensor. I started the truck back up and it idled perfect so I pulled it back out of the garage and headed down the driveway. It almost immediately started running rough again and barely had the power to go up a small hill. I pulled back in and tried unplugging the ICP while it was running, which made a slight difference in the idle but still very rough. I plugged it back in and the idle progressively got worse until it was chugging really bad. I shut it off after that and haven't messed with it again.
What might have happened? Could it be a bad sensor or transmission position sensor in the new trans? Is it just coincidence that this happened with a transmission swap? I am going to get a new ICP, but if there is anything else I can try/check before I can pick up the ICP on Monday let me know.
Ford 7.3L Power Stroke (1999-2003) :: Running Rough When Accelerate / Bogs Down And Looses Power
I was wondering if fuel injectors throw a code when it goes out. I have a 02 7.3 been running rough when you accelerate bogs down and looses power not sure but sometimes gas light would come on knowing I have gas in it could that be a sign of the sending unite and that's why it runs rough..

I have a 2001 F350, 7.3. My service engine light came on and immediately the truck started to run rough and lose some power. I've checked the under the cover connections and they were both connected, I replaced the cam position sensor and I still have the same problem. The worse part of the hold thing is that there are no codes stored so I'm flying bind. Where to go next.

I had an HPOP line burst and soak the engine compartment with oil. I replaced the line and degreased the engine and rinsed it off. I started the truck and let it idle for 15 minutes or so before driving it. On the way home right after a shift it started chugging and running terribly. The check engine light was on as well. I limped it the mile or so home and shut it off. I restarted it and it runs just fine. I checked the DTC's with Forscan and there were a bunch of things that were mostly related to the HPOP and the MAT sensor that was shredded when the line blew. I left the hood open to dry out today and I'm hoping it is just some water in a connector. Does that sound plausible?
View 6 RepliesFord 7.3L Power Stroke (1999-2003) :: Running Rough And Cannot Pull When Put It In Drive
I bought a 99 7.3 been in the trees for a few years pulled it home and now trying to get it running. Did a service new filters and oil fuel too. I can get it to start and will run but runs very rough and if you put it in drive cant pull its own self. I don't have a check eng light on. And found out my scanner is a pos lol. it will hooked up and then try to pull codes and loses it connection. But that's the scanner will not work on my other 7.3 as well.
I am making high pressure oil checked off the rail with gauge and it will build up to 2000 psi when I rev it. but missing like crazy. I swaped the pcm and idm out of my running 7.3 and it didn't change a thing. I have checked the pass though and they are fine. pulled drivers side valve cover off and no oil leaks when running and rockers are fine. new ipr valve as well too. I know I need to get a scanner to talk to this thing better.
Ford 6.7L Power Stroke Diesel :: Lost Power For Running Board Lights
I added LED lights to illuminate the running boards on my Lariat. Did this about 15 months ago and all was fine until this week and I noticed they weren't coming on any longer. Both sides are out of commission. The running board lights on each side are wired to the respective plug for the running board lights on each side. The interior lights that are on the same circuit work fine (fuse #12 in the passenger side fuse box).
So I'm scratching my head trying to figure out why both sides have gone out at the same time but the fuse is ok. It's winter here and my truck doesn't completely in the garage so I'm hoping to limit my time lying under the truck out in the cold, on a wet floor! I thought there might be another fuse in the engine compartment fuse box but there isn't, at least according to the manual.
