Honda - Accord :: 1999 - Engine Dies When Pedal Pressed Down / Revs And Then Quits When Pedal Is Pressed Slowly
Ok, did an intake manifold cleaning on my 99 Accord the other day, and now I have problems...
Long story short, some time ago my car started to have a very rough idle. Took me awhile to find the problem. Turned out the air hose, between the filter and throttle body, had developed a big hole on the underside. So I replaced it and while I was at it used some throttle body cleaner, spraying into the intake manifold chamber. Lot of junk blew out the tailpipe. The car ran much better, but the idle could still be a little rough. I ran it that way for awhile, and finally the other day decided there was probably still some junk in there and it was time to really clean it out. So I took ff the throttle body and intake manifold housing. There was a lot of junk in there! The small intake on the passenger side was completely clogged shut. (I understand this isn't surprising on these cars.) I used a bunch of rags and 2 cans of Valvoline throttle body cleaner and a lot of elbow grease and cleaned it out. I was thinking to myself that whatever I didn't get with the rags flushed through OK, but I didn't want to take the whole intake manifold out.
So I put it all back together. (I took a video before I started, so I'm pretty sure it's all back together right.) But now I have problems. The car starts. It idles fine mostly, but can be a bit rough. But the trouble starts when I put the pedal down. If I do it in Park, well, if I push it quick the engine just dies. If I push it slow, the engine revs then quits, revs and quits, over and over. Similar if it's in gear. If I push it hard, the engine stalls. If I push it gentle, it revs up, but chugs along a bit.
I've run some seafoam through it, thinking it was clogged up with all that junk, and sure enough, lots of smoke comes out, but nothing is improving so far. What have I done wrong?

View 3 RepliesGolf VI R :: Clutch Pedal Vibrates When Accelerator Pressed
If I'm at part throttle and i press the clutch pedal in about 2-3 inches, leaving the clutch still fully engaged, i can feel a really rough vibration in the clutch pedal. it stops vibrating as soon as i let off the gas. and i'm only giving it a little bit of gas, mind you.
If I'm at idle, and i have the clutch depressed all the way and rev the engine, I can feel vibration in the clutch pedal. My 6-speed MK4 did not do this, not in the slightest. Is this normal for MK6 or do I have a problem?

I have an issue with my 1999 Ford F350 7.3L diesel and stalling when the accelerator pedal is pressed and released.
Background: Initially the truck would not start, and from there here are all the things that I found wrong and replaced. (keep in mind that I troubleshot all the issues and every part that was replaced was proven faulty)... Starting with the glow plugs, all but 3 were faulty and not making a connection to ground. (only one broke off in the head, but I was able to get it out with out getting anything in the cyl)..
Valve cover gasket and harnesses, this is to include replacing the connectors on the engine harness cause both sides of the connectors were broken. The ICP was leaking into the connector and breaking the connection to the PCM, so the connector was cleaned and the sensor replaced. No issues from that now.
The IPR was replaced cause the oil pressure was erratic and not stable when I had my pressure gauge hooked up testing the pressure. After that was replaced the pressure was ok, and it climbed with RPM's and fell back down like it was suppose to. I could not get the PSI up to 3000 PSI even at full RPM's, but it did not drop past 600 psi.
The fuel tank was recently replaced, and all the fuel was removed and "fresh/good" fuel was put in. The fuel bowl was cleaned out and the filter replaced. (the fuel bowl did have a lot of crap in it like rust and dirt). Fuel pressure was at 95 PSI last time I checked, which is higher than the recommended 60 to 65 PSI.
That being said the engine did start and run, but was very rough and missing. So I did all the injector o-rings. Some o-rings were starting to split, and others were not sealing like the copper washer on the injector tip. I could tell by the amount of crap in the end of the injector. ( not the tip, but where the injector contacts the injector cup. There must have been water in there or something cause that part had all kinds of crap around it)
The engine smoothed out after a couple day of running it, but it would still stall when it was cold. The block heater was replaced cause it was falling out. The oil was changed and the filter too. The CMP sensor was changed just because I know they will cause the engine not to start. I had a "known good" truck that I can swap part to and from, and I did a lot of that thus far.
Swapped the IDM, PCM, EBP sensor, MAP sensor, all relays inside the engine and in the cab. I was looking for the barometric pressure sensor, but from what I have read thus far that is a calculation in the PCM between the MAP and the EBP sensors. The diode to the PCM is good,I checked the harness for rubbing by the 42 pin connector and by the LF fender but I did not find any chaffing or rubbing on any wires. The ECPR was wired together, so I fixed it so that it is no longer that way, and the waste gate for the turbo was wired open. I took the wire off and made sure the linkage worked and it did move. I tried to lube up the valve in the turbo for back pressure, but I'm not sure if it worked or not.
I also swapped out the oil pressure sensor and the oil pressure temp sensor on the HPOP Reservoir, and blew out the EBP sensors tube. (air went straight through the tube with no restrictions.) I did a buzz test and all the coils checked out ok. I also did a contribution test and only three cylinders were identified as having some kind of issue. (but this is not enough to cause the engine to stall..) The only current codes that I have are the air intake heater, and the EF feedback not detected. Neither of which would cause the engine to stall in my opinion.
Symptoms:
When cold: The engine will start and idle just fine, but when the accelerator is pressed and held to 1000 RPM's the engine will sputter like its missing and surge up and down between 500 and 1100 RPM's. If the accelerator pedal is pressed quickly the engine speed to increase then fall down and stall. It seems as if the PCM is shutting down and starting back up. ( Like the key is turned off and then back on quickly, but the engine doesn't recover)
When warming: This issue becomes more erratic, but when hot the engine is fine. No issues, and it will drive all day long with no hesitation.
The truck has over 200K on it, but I know it will go more! It is a mannuel tranny, and is a 4X4, and I love it, I can't get ride of it just yet.

Yesterday the Check Engine light came on, the code was P1121 Accelerator Pedal Position Sensor Error, Performance/Range. I have not yet had the pedal replaced related to the recall (bad me), is the sensor incorporated in the new assembly or is this separate and I'll need to replace it?

Just Bought an 05 Passat 1.8T about month ago. It has 80k miles on it. I was driving down a road going about 40 mph and all of the sudden the engine is not responding to the pressing of the accelerator, everything else was normal. So I coast into a nearby parking lot. Car won't start, all lights come on and but would not turnover. Got it towed, few days go by, now car turns over but immediately dies.
No codes read on it. The dealership will not cover a diagnostic or anything fuel related.

I have an '03 Ford Explorer (V8) and recently had a rebuilt engine installed (at 135,000 miles). As soon as I got the car back, the engine whined and it's getting louder. The whine starts immediately but it louder when the accelerator is pressed. The sound reminds me of a car with bad power steering, but it's so much louder and doesn't correlate to turning the wheel, but pressing the gas pedal.

I've a 2004 Prius. Had it for 3 years. 40,000 miles. No problems what-so-ever. 55 to 60mpg without any effort.
During the winter I noticed that when the petrol engine switched off - there was a jolt. (It used to be totally imperceptible.) Nothing drastic - I have to be on smooth tarmac to notice.
My Toyota dealer said this sometimes happens in cold weather. However, the weather has warmed up - and I can still feel the jolt.
Don't know if it's connected, by the central display diagnostic check tells me...

Prius (2004-09) :: 2006 - Jumpy Transmission When Car Switches From Electric To Gas Engine
I bought my 2006 Prius used and I had just put it over 100,000 miles. The dearlership has replaced the HV battery under warranty and suggest that I replace a slightly leaking waterpump and cracked belt, said nothing about the transmission.
My concern is, my transmission. When the car switches from electric to the gas engine, the car jumps a little bit, and it's an obvious and not smooth shift. And when I put it in Park, the vehicle rocks back and forth a bit, shifting a few inches before coming to a still position. Is this standard with other 2006 Prius? I drove my friends 2007 Prius and the shift seems smooth and it doesnt rock when you put it in park. Should I be concerned and if so what should I do?

View 7 RepliesPrius (2004-09) :: Engine Cuts In And Out At Above 70mph In Snowy Weather
It has been very cold and snowy recently. This morning when I left for work it was about -6 degrees F. After about 15 miles into a 55 mile trip down a snow free road with a 70 mph speed limit I had an unusual experience. Cruise is set at 75 (based on GPS), had to slow down to negotiate around a couple of triple trailer trucks. When I selected resume with the cruise, the engine revved and then cut in and out as it tried to accelerate to 70 mph.
No trouble lights or dashboard warnings. I turned off the cruise, and feathered the throttle and edged back to 75 mph, and then reset cruise. I rolled down the road for another 10 without issue. I again tried to duplicate the problem and I was unable to reproduce the engine cut out. When it malfunctioned, it felt as if the ignition was switched on and off. What might cause this erratic engine behavior?
Prius (2004-09) :: Engine Cuts Out After Staying On For A Few Seconds When Starting Up Again
When trying to drive my car out of the garage this weekend, it started backing up and then it stopped. It would also not do anything when I put it in drive. Next, the engine cut out. It would only stay on for a few seconds when starting it up again. It continued to do this. I had the car brought to my local mechanic who specializes in foreign cars. He called me today and said my car will not talk to the computer. He stated it must be the hybrid battery. He told me I need to take it to a Toyota dealer. My question is how to know if this battery is truly out and there is not another problem? I have a 2001 Prius.
View 3 RepliesPrius (Gen 3) :: Chirping Noise When Brake Pedal Pressed
I was wondering if this problem is the "Barking" noise that keeps coming up the search or is it another problem. I will include a link to the video down below.
To start off, the Prius is 2010 Prius II and has 120k miles on it. Great Car. Only other problem was AC compressor dying at 90k.
The chirping noise happens when the brake pedal is pressed and does not go away until the release the pedal. It makes the noise regardless of whether the car is on or off.
It makes the noise when the car is stopped and or when the mechanical brake engage at between 0 and 6 mph.
Noise does not occur when the brake switch is removed. Not valid solution since the brake lights will stay on. It does not affect the performance of braking.
Here is the link to the video .... .... ....
