Ford 7.3L Power Stroke (1999-2003) :: Shaking At Higher Speeds - 40 MPH And Above - Loss Of Power

I have a 2000 Excursion 7.3, 6 position tune, and exhaust as far as mods (on truck when bought). Last couple of weeks I get no power while on the throttle, foot on the gas and the whole truck shakes at higher speeds - 40mph and above. At first it wouldn't go above 60 or so, would hit the gas and Rpms would just stop not be able to generate any further power. Changed the IPR, ICP, and CPS.

I still get the high/low range ICP codes, P1280, P1281. First night the IPR was changed I got it up to 90mph and thought it was all solved but got a little shake right at the top and I let off the gas. Next day back to square one and has seemed to get progressively worse, almost wasn't able to make it up a hill by my house not even going 20mph, but it's like intermittent. I have a scan tool, here is at idle and at around 60mph ....

Ford 7.3L Power Stroke (1999-2003) :: 2000 F250 - Major Power Loss And Shaking

I've got a 2000 F-250 with a 7.3. The other day I was driving down the road and it lost power and my foot almost went to the floor. I was at the bottom of a hill when it did this and I was running 60 mph. By the time I got to the top I was running 20 mph and had the truck to the floor. When I was driving it home it was tacking around 1800 rpm and my egts were only at 125 degrees. I know I'm not getting fuel. I thought it could be the fuel filter so I changed it. Still no luck. It'll start back up but it dies if I take my foot off the accelerator. It shook terrible when I was driving it home too. Is it injectors, uvch, hpop, or something else?

Mazda - Protege :: Power Loss And Engine Shaking A Little

'99 Mazda 323 Protege. Manual, fuel-injected, 4cyl.

Engine code: CE04D16

So just recently started having troubles with the car. It ran fine then all of a sudden I lost what felt like 15-25% power, and the engine felt like it was shaking a little.

When revving, then engine would shudder. Idle rev went from just over 1000 to around 500. there was very little pickup when increasing speed. I can only assume it is losing a cylinder. But since it is fuel injected, people have been saying check the leads, (from where to where?), the distributor, spark plugs etc etc. Now for the last couple days it has been jumping backwards and forwards, from regular to slow.

What is the problem, can I fix this myself, or do I need to take it to a mechanic?

Santa FE SM (2001-06) :: Severe Shaking And Power Loss Then Stalled

Today I took my AWD 2.7 Santa Fe out. All seemed fine until I made a turn... I noticed I was loosing power and came to a stop, despite pressing the gas pedal fully. The car then started to vibrate extremely hard and all of the dash lights came on. The car stalled completely. I tried to start the car again, but it took a few tries. The car shook severely in park, but when put in drive immediately became much worse and then completely stalled. I did this many times trying to get out of the street. I finally got it to work good enough to get off the road - I did however notice that it would not shift out of 1st gear. It had very high rpms, but refused to shift.

I am guessing this is the crankshaft position sensor? Could this be a MAF problem? I believe I read on this forum about high humidity making Santa Fes go crazy - it has been over 95% today, and raining. I managed to get the car down the road to a shop we trust. They are going to try and read codes later.

Elantra MD (2010-15) :: Power Loss For A Second / Car Shaking With Grumbling Sound

My 2014 Elantra Limited Automatic 1.8 has just developed a problem tonight. I was backing up my driveway, when the car began shaking, making a grumbling sound, and felt like it lost power for a second. I pulled out of my driveway and tried backing up again about 5 more times, and it kept on repeating the problem. The car was leaking what appeared to be a clear fluid which stained the garage floor. It drives fine going forward, and only has 4,000 miles.

Ford :: 2007 - While Accelerating Loss Power And Shaking At Stop - Won't Fire Again?

I have a 2007 Ford Fusion 4.0L AWD. One day I went to pass a slower car and accelerated rapidly, but the car responded with loss of power and shook to a stop and would not re fire. I took it to the dealership and they said two cylinders were not firing and a fuse was blown. I looked on the internet and some people said their coils go bad or plug wires. I asked the dealership if that was the cause and they said absolutely not, but it's the ECM. They replaced the ECM and 2 days later my CEL came on and I took it back to the dealership and they told me my catalytic converter was bad and I could drive it until I had the money to replace it. Then a couple days go by and I was passing a tractor on the highway, I slowed down to 45 mph to make the pass and as I began to accelerated I felt a thunk, then about a mile later it started cutting out and shaking. This time it would re fire but idle rough. I tried on/off 3 or 4 times then it idled o.k. I then took it back to the dealership and this time they said it's all 6 coils.

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).

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?

Ford 6.0L Power Stroke Diesel :: Rough Idle At Startup And Shaking - Lag In Power And Vibrate On Highway

This morning I noticed when I started the truck had a rough idle shaking truck. The truck felt weak. Boost would go up but truck felt like it was in sand. While coasting on the highway at 50-55mph the truck not only lags in power but vibrates viciously until the overdrive kicks in that vibrations in cab and ssteering wheel go away.. What might be going on?

Ford 6.0L Power Stroke Diesel :: 2004 F250 V8 - Hard Start / Rough Idle / Shaking - No Power When Cold

I'm new to diesels. I just bought a 2004 F250 with the 6.0 V8. I have the high and low circuit, contribution codes on cylinders 4 and 8. I've only had the truck for a few days but I've been reading a ton. The symptoms are hard start, rough idle/shaking, no power when cold. When it heats up and I'm over 2000 RPM it seems to be just fine. Even when hot and below 2000 RPM it does ok. I've check the FICM. It reads 48V with key on and 48V running. My plan is to do the following:

Change the Fuel Filters
Change the oil filter
Change Air Filter
Change oil with 5-W30 synth and I have both Hot Shot/Rev-X

If that doesn't work, I'll replace the two injectors. How does that sound.

Ford 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.

Ford 7.3L Power Stroke (1999-2003) :: Power Loss Throwing P0472?

I just recently bought a 199 E350 4x4. I changed the injectors and it drove a little bit better but was still lacking power and was throwing a p0472(exhaust back pressure code) and a p0113(IAT sensor circuit hight output) code. Last night i put a new ebp sensor and the truck came back to life for about a half mile or so then went right back to the way it was. I took the sensor back off and cleaned it in case it some how got clogged from my short ride. It surprisingly did have some soot in it which i cleaned out. Also blew air into the ebps line while still mounted. Put everything back and still nothing. What could it be? Could i possibly got a bad ebps?

Ford 6.0L Power Stroke Diesel :: Loss Of Power And Lots Of Black Smoke

Today I was riding along and all of a sudden I noticed a loss of power. I look in the rear view mirror and get into the pedal and a lot of black smoke. When I get to where I'm going and stop I noticed the idol was a little loopy. I never saw a check engine light. I have the Edge insight. I had two codes. P1000 OBD System readiness test not complete. P2290 ICP TO LOW.

When I would reset the codes the P1000 came back instantly every time. I parked the truck for about an hour. When I started it back up everything was normal. The power was back and no smoke. This happened two more times throughout the day. I have heard people describe a sticking EGR Valve causing these symptoms. Is that where I should start looking or is the ICP the culprit or something else?

Ford 7.3L Power Stroke (1999-2003) :: Instant Loss Of Power But Runs

I am going along and the power just goes away. Sometimes it is a 50% loss other times it is an 80% loss. I hooked up my scanner and found an IPR code. I replaced the IPR and connector, nothing changed.

As the scanner info shows the Duty Cycle and Pressure track about identically until something goes wonky. When I loose about 50% power the pressure will not get above about 1500 psi but the duty cycle will run up to 60%. Other times when I have a bout an 80% loss the pressure and duty cycle both track low, no more than 1200psi and about 20%.

Ford 6.0L Power Stroke Diesel :: 2004 F250 - Sudden Loss Of Power

I have a 2004 F250 6.0 DuperDuty with about 170,000 miles on it, so far no major break-downs, just a starter and a blinker relay, but now I have a problem.

When I start now, the truck starts fine and it sounds fine, but it has almost no power even if I floor the gas peddle, there is a delay of like 2-3 seconds and then responds slowly, like some tractor. Eventually it starts to move slowly, and after it warms up (after a few minutes), the gas peddle responds more normal.

Also - at about 45mpg, at lower RPMs about 1250, the engine starts to shake (weird), it doesn't do it at idle about 850 RPM, or when I get it up to about 1800RPM+, but at about that 1250 RPM it does do it, luckily I driver locally for a few miles.

What could this be ? What exactly happens when I press on the gas peddle, what systems are involved and in which order?

Ford 6.0L Power Stroke Diesel :: Brief Loss Of Power When Accelerate While Driving - Bad Injector?

Occasionally when I'm driving, I'll accelerate and get a brief loss of power, then it'll pick back up, followed by a puff of white/blue smoke. This usually happens when the oil is over 120*, but not quite to full operating temps. It doesn't happen every time either. Only 3 times in the past week. Otherwise, there is a very faint haze of white smoke that seems to be constant. It is very difficult to see unless against a dark background. Oil level is good, I check it once a week, no rising or lowering levels.

I pulled the EGR yesterday, all good, although a tad dirty. Cleaned up no problem. Haven't had a chance to do a bubble test yet. There are some DTCs, but I can't remember off the top of my head what they were. I'm about to go clean the inside of the truck, so I will pull those and update in a few minutes.

Truck has about 148,500 miles.

Torque Pro lists these codes: C1145, P0299, P0677

Ford 7.3L Power Stroke (1999-2003) :: Power Loss When Exiting The Freeway

For some stupid reason, my truck decided to lose power today when exiting the freeway. D/s egt gauge verified it with no increase in temp when stepping on go pedal. After about a minute, I could feel it gain power. So, rolled into fuel station, and topped off tank. While filling, I popped the hood and started messing with the uvch and looking around. It was then I noticed that darn hose riding on top of a ton of wires. Pulled said hose up and sure enough, a wire is shafed clean off of insulation. Anyway, something to check while looking around under there....
