Ford F-150 (2004-2008) :: 2005 - Idle Really Rough / Revs Will Rise And Then Drop Again If Blip The Throttle
I just locked out the cam phasers on a 2005 f150 with a 5.4. It now idles pretty rough. If I blip the throttle the revs will rise and then drop again, and it barely catches in time to prevent a stall. If I continue to tease it this way I can usually get it to stall. I'm getting no CELs or anything, but I intermittently will get a P035x code (it seemed to rove. I've gotten cylinder 1, 4, 6, but not consistently.). I have chased those around by swapping coils, checking/cleaning the connectors, etc.
I am kind of thinking that these codes are a symptom of my idle issues, and not the actual problem. What could I have done wrong? Could it be a vac issue? I had basically the entire ECU harness and all the vac lines disconnected to do the job, but as far as I can tell everything has been reconnected to the correct locations. I did have an SCT tune done to remove the phasers in the ECU. I installed it and still have the issue, so for now I am on the stock tune just to eliminate any variables.
Could my tune be the issue? Is this how you would expect the engine to behave with locked out phasers and no corresponding ECU tune?
Elantra MD (2010-15) :: Shaking When Taking Foot Off Gas Pedal
I have a 2016 Elantra that was bought brand new in October of last year. Since about January, the front end of the car bucks when taking your foot off the accelerator to slow down. The brakes do not need to be applied to cause this to happen. When I say it bucks, it happens repeatedly for 3-5 seconds and everyone in he car can feel it. This happens mainly when going at speeds of 20-30 mph and when going short distances such as stop sign to stop sign or in bumper to bumper traffic. If I put the car in neutral the bucking instantly stops. Unfortunately this doesn't happen every day so the dealer has not been able to replicate it as of yet.
View 5 RepliesAzera TG (2006-11) :: Headlights Dim When Braking Or Taking Foot Off Gas
I have a 2006 Azera Limited, and over the past few months I have noticed that when driving it is dark, my headlights will dim drastically either when I brake under about 30 mph, or when I let up on the gas going around 30-35 mph. I can see the tach drop to below 500 rpm, and the interior lights will also dim. It frustrates me because I took it to the dealership yesterday to have them look at this, and they said they couldn't see anything wrong. They said there were no error codes, the alternator was fine, and the battery looked fine. They said "just keep an eye on it" when I picked it up yesterday.
This morning on my drive to work it happened about 5 times. It bugs me because I feel as if it is going to stall, and when the lights dim like that, I can't see!! It's usually brief - about a second or so - but still. What it would be, so when I take it back to them I can tell them what is going on? I love my Azera, but to be honest I don't know much about the inner-workings of cars, so where to start if I was to look at it myself. It seems electrical, but they assured me that nothing was wrong.
Touareg :: 2006 V8 - Grinding Noise Specially While Foot On Gas At Cruising Speeds
I have an 06 Touareg V8 with AWD, auto tranny. No leveling suspension. And when I drive it specially while my foot is on the gas at cruising speeds there's a grinding noise coming from under the car. When I step off the gas it is gone or when I am accelerating hard I can't hear it. What could it be? It's driving me and my ocd insane!! I think it is drivetrain related (differential, wheel bearing, etc.) but not the transmission as I can still hear it while coasting in neutral.
View 3 RepliesPrius (2004-09) :: 2005 - Noise When Taking Foot Off The Brake
I have 2005 Prius, 53K miles on it. Bought it as used car few months ago. It has been running great since then.
Since last few weeks I have been hearing a soft beep every time I take foot off the brake. Today I had my windows down while driving and I realized that the soft beep is actually a loud noise like squeak or beep. I can hear a noise every time I take foot off the brake (NOT when putting foot on the brake).
Anyone can standing near the car or other car drivers at red-light can hear the sound too.. This happens when- the Car is in D, I take foot off the accelerator and press the brake (to slow down or complete stop) then take foot off the brake.
Touareg :: Interior Overhead And Foot Lights Taking 5 Minutes To Go Off?
The headlights went out on the automatic "arrive home mode" more than the programmed 15 seconds. The interior overhead and foot lights took as much as 5 minutes to cease and desist.

Golf IV R32 :: Rapid Deceleration After Taking Foot Off The Gas - Getting Code P3801
Today I noticed that it feels like my R decelerates rather quickly as soon as I take my foot off the gas. In my old GTI, it seemed that it would glide in whatever gear I was in for a while. In this, however, It seems to slow down VERY quickly if I am not pressing in the accelerator.
Am I just crazy, or could this be an actual issue? My only thoughts are that the emergency brake cable is too tight and the brake is stuck on a little bit? Any thoughts?
I do have a CEL on from code P3801, which I read is most likely the ECT sensor. I know this may cause a loss of gas mileage, but could this be the culprit of this (almost) issue?
Toyota - Camry :: 1992 - Stalling When Come To A Stop And Taking Foot Off The Accelerator
I have a '92 toyota camry that we just purchased and put a new engine in... now it's stalling when you come to a stop and are taking your foot off the accelerator. we've tried a fuel injector, a fuel clean, fixed vacuum leaks, and replaced the fuel filter, and fuel preside regulator... it's still doing it and is getting worse.
View 1 RepliesCamry :: 2009 - Idle Drop Engine / Car Shaking When Brakes Applied And AC Is On
Here are my issues.
1. In drive under load during braking especially when the AC is on the car shakes. I can put it in to neutral and it works but when in drive or reverse especially with AC the car shakes. (not just a little bit)
2. The RPMs are settling around 400-500 so the stuttering makes since.
3. Feels like everything effects my Idle RPM speed (breaks, steering, AC, power windows lol!)
I am thinking possible fixes from research
1. ECU Reset with everything on AC/Lights/ Im planning on mashing on the breaks 2 see if the extra power usage work.
2. Throttle Body cleaning
3. Alternator could be bad
Corolla / Matrix 2009-13 :: 2012 - Engine Idle Speed Will Slowly Drop From 800 O About 650 - 600
2012 Corolla S 5 speed manual. Just bought the car in September. CPO with 19k miles on it when purchased. Now it has 22k miles. The "problem" is as follows:
After driving the car around for some time, meaning fully warmed-up, when I come to a stop at a light the engine's idle speed will slowly drop from about 800 (where it's as smooth as glass and I can't even tell the engine is running) to about 650-600 and there's a noticeable shudder in the wheel and in the whole car. It lasts for a few seconds then the RPM goes back to normal - just as if it's correcting itself. This happens with nothing running except the radio. No fan, no A/C, nothing.
The only thing I could think is that the radiator fan is kicking on and causing the alternator to work harder? Considering this is a manual is it safe to rule out any kind of transmission issue?
I didn't notice it when I test drove the car, and honestly, the car I was driving before made so much racket that this Corolla sounds like a luxury car by comparison.
Ford Excursion :: Louder Roar Coming From Rear End When Taking Foot Off The Accelerator Without Pressing Brake
After putting my front end back together except new springs, new shocks, and new track bar, just to give everyone a little history of what I've done to it. I've had it for 8 months and maybe put 1000 miles if that because of working out of town a lot and the front end torn apart. I've noticed a louder roar coming from the rear end when taking my foot off the accelerator without pressing the brake. It feels like the tow button is engaged, but isnt. I have no issues with handling besides knowing it still needs alignment. I'm taking it to the dealership tomorrow for a 4 wheel alignment. It sounds and feels like I'm riding on mud terrain tires.
View 14 RepliesTiguan :: 2009 - Sputtering / Stalling And Rough Idle
09 tiguan that was bought in august of this year as a certified pre owned and has a warranty on it until 60k miles or 2014. Recently there has been some issues with the car stalling out and sometimes having a very low rough idle and then the idle will pick up and the car will surge slightly then it will be fine for a while. I have my suspicions that it is because this is my fiance's car and she has been putting mid grade gas in the car lately. Also we cannot get the fuel door to open now is there any tricks on getting it open?
View 3 RepliesWindstar :: 1998 3.0 - Drop In Revs Causes Engine To Stall
My wife has a 1998 Windstar 3.0
Prior to going out yesterday, I noticed that the van seemed kind of 'jumpy' when idling - the timing was a bit sticky and inconsistent and kept seeming to try and right itself. I stuck the accelerator down and it ran perfect when it was getting gas but started 'stagering' again when I took it off.
So my wife went out to walmart - a 30 min drive (we are in the country) - and all was good till she was turning the corner into the parking lot and the engine stalled. It was your standard stall - power steering went out but all other electrics kept going etc etc.
She sat there for a minute - put it in park - then fired it right back up again. After running into walmart, she just drove home as fast as possible to reduce the length of time it had to happen again.....
So while there are, Im sure, a plethora of possible issues - I was wondering about the IAC value? How could that be responsible for the parking lot though - doesn't it only act when the car is stationary?
The sort of thing was happening about 3 months ago, and I ran seafoam through the fuel - which seemed to work for a while.
Golf VI R :: Revs Slow To Drop When Changing Gear
I just picked up my new R (Rising Blue 2 Door w/ S-Roof & Nav) yesterday and love it, except for one thing. When accelerating and changing up through the gears, the revs seem very slow to drop after lifting off the gas and dipping the clutch to select the next gear. It is like there is a delay between me lifting off and the instruction getting to the engine.
View 6 RepliesAccent RB (2012+) :: Engine Shudders When Takeoff - Revs Drop To Almost Around 300 - 400
After the car has been sitting for a while (say about 8 hours or so) I will turn the car on and I will always wait about 30 seconds or so before moving off just to let the oil start moving around. If I go to take off the engine shudders and sounds like its about to stall and the engine revs drop to almost around 300-400 revs then suddenly come back up.
Now I drive a manual car and I know there will be people there that will say I obviously cant use the clutch very well. This happens from anywhere from a flat to a decent incline in rain or sunshine, night and day, and all different external temperatures.
But that isn't all, the kicker is if I give the throttle a quick jab to bring the revs to around 1200-1500 revs, go to take off and the car is fine. ONLY happens once after sitting around for a while, basically after the engine has a good time to cool off to completely cold. Little side note, this has been getting more frequent over the last 3 months.
Golf IV / Jetta IV :: Revs Just Drop Down To 0 And Engine Shuts Down While Slowing Down
Looking for some hint regarding V6 AUE ? Regardless if engine is warm or cold, sometimes happens to me that during driving, while slowing down and pressing on clutch pedal, revs just drop down to 0 and engine shuts down (vehicle still moving). This usually happens while changing gears from 3rd to 2nd on low speeds in city, or while slowing down to full stop in 2nd gear and pressing clutch pedal.
While this happens, I quickly switch off the ignition and start the engine again, which is tricky and potentially dangerous, since vehicle is still moving but my power steering and brakes are not functioning because of stopped engine.
Some relevant info...I have K&N cone air filter intake and ECU is remapped by BTS Racing (German tuning house).
Car is running and pulling normally. In all other regimes of driving, there are no issues or whatsoever.
Camry :: 2003 V6 Stalls At Stops Randomly / RPMs Drop And Then It Revs Up
I have a 2003 Camry 3.0l v6. Stalls at lights random.
Currently the car stalls at stops but this doesn't happen all the time it can go a month in between the problem occurring its very random. While sitting at a light the rpms drop and then it revs up and cycles like that for quite a while. This will also occur while cruising at a low speed while I'm just coasting the rpms will go up and down. I can compensate while stopped by power braking and keeping it at its normal idling rpm. I have no check engine lights and can't seem to determine what would be causing this issue.
Tiguan :: 2011 SE Bucking Repeatedly When Foot Is On The Brake
My 3 month old Tiguan will buck repeatedly when my foot is on the brake after shifting from P to D or S on occasion. If I put it back in Park then shift back to drive or sport, it goes away... I took it to the dealer and they couldn't reproduce the issue after a few hours. It has happened to me a few times now, and it is quite concerning. I'm guessing it is either the trans or maybe the Turbo baffle causing the issue, but can;t find any info online.
View 8 RepliesTiguan :: Heavy Clunking Noise From Right Side While Taking A Right Turn
I'm having an issue I cant seam to track down. I am getting a bad clunking sound from the right side while taking a right turn. I was thinking it was an axle because it was flopping around when I took it out to inspect it. So I replaced that and also the ball joint because it was ripped. Took the car for a test drive and still getting this banging sound. I went back and checked the suspension bolts, tie rod, and cant seam to find my issue. I know bad wheel bearings make more of a howl but could they also make a bad clicking sound? or do you think the issue is worse than I was thinking and might be the diff?
