So my cars idle has been revving slightly from 9 to 10. siting idle sometimes it will do the same but from 10-11. when it does it shudders the car slightly.
So I stop by a local auto parts and get the check engine scanned.....it comes back as Idle control too high.
So What is that? The guy working there who seems to have some knowledge of turbos said it was either some control piece or a vacuum leak.
When I'm driving and i let off the gas and come to a stop, my car dips close to 200rpm below idle and shudders slightly and goes back to idle.
My car just doesn't seem to have the amount of power that it should. My roommate has a 1.8t jetta with just a few more mods than I do and his car seems so much faster. I put an APR chip in my car and i still have a lag in the throttle..my car jerks..and it just doesn't seem that my car has the right amount of power.
My car shudders (headlights flicker, dash lights flicker, and car feels like it's choking/almost stalling) when I sit at an idle. Today it got super bad and the abs light flickered on and off when ever it would "shudder".
Live in so-cal where we just had heavy rain the last 2 days so I'm thinking it may be a wet ground somewhere but I'm not an electrician so I wouldn't know for sure.

Nothing done to it except straight pipe and intake...
When idle, and especially when cold, my R engine tends to do some popping, I can see the RPM drop slightly when this happens and can also hear and feel it in the car and from the engine and exhaust. This only happens when idle, I have no other issues, no drop in performance and no CEL.
It actually has done this for a while now but barely noticeable. Now since 2 weeks it has gone worse to the level of being annoying. What this may be ? Injectors maybe ?
Is it possible to slightly raise the Idle speed of our R32s?
And if so, how is it done?
Is there a procedure with Vagcom?
So I just noticed now that my car is popping slightly at idle occasionally...It doesn't do it all the time and the idle is kinda lumpy but always holds at 800-900. Sometimes it drops a bit lower.
Also when starting it up in the morning, or when the engine is cold it doesnt rev up to 1500rpms it just starts and immediately drops to 800-900??
When I press on the gas and keep the pedal at one spot, say 2000rpms, it slowly drops down to 1500??
This is my first new car, but I am assuming the idle should be pretty smooth. I feel my idle and it feels sort of rough. Almost like there is a slight misfire but not that intense.
One more question, car burning oil?
@ 7500 miles I was down a little more than a quart and now @ 14,100 I am down almost a quart. That is slightly alarming.
My Expedition started to shudder on a drive when I got it up to 55 MPH. I drove for about 15 minutes and parked well I drove it again and it started to do the same thing. Now the Service Engine Light came on. What the cause could be. (2000 Ford Expedition EB Ed. 5.4l Triton).
View 12 Replies95 350 Tbi does well idling in park and on the highway but at idle speeds it shudders. And if i slow down to make a stop it shudders til i get my speed back up or floor it. It have new plugs and wires, fuel pump, fuel filter, air filter, TPS, IAC, new throttle body gasket, new vacuum lines. What else could it be?
View 1 RepliesMy car started a rough idle last night.... Pull to stop light, in gear, a/c on #1 and car shudders and acts like it's going to stall..... Went away as I drove a round a bit.....back this a.m. (after the warm up program ran) drove it a bit and was sporadic.....and even went away...then came back.....
Its worse when car is at stop and in 'D'.....little better with a/c off and/or in neutral......it finally threw the CEL today....... I had the fuel pump recall done about a month or two ago, car has 36k+ on it...... Anything I should have the service dept look for aside from what the fault codes might read?

So my story starts simple enough; I ran out of gas in my buddy's car, filled it back up, it finally started but ran like >poop< for the first 10 min or so. Finally after coaxing for 10-15 min, she stays coming around. After 30 min or so of driving, I could drive her all I wanted, so long as I didn't let it idle below 12-1500 rpm. If I did that, she'd kill, and stall out. Well I drove her the other day for most the day and it seemed the kinks were worked out. So today when I tried to drive her round the block for a final check, she up and dies, and hasn't started since. I've replaced the fuel filter, checked the intake, and dropped a can of sea foam in to the tank to boot, but no dice.Signs and symptoms seem to mimic a bad mass air flow sensor or possibly a clogged catalytic converter, with the exception that it only shudders and acts congested on low rpm's and doesn't choke out at high revs.
View 15 RepliesI have a 1993 Mazda MX-6. For the past 2-3 years, my car shudders when it idles or goes less than 10 miles an hour. More and more lately, it has been shutting off completely when I drive slow or come to a stop. The first few weeks it was happening, one day while in a Burger King drive-thru (of all places- how embarrassing), it shut off and I couldn't get it to start again.
The mechanic I took it to replaced the distributor to fix it. It has not had a problem starting anymore since then, but it still shudders very hard. Could it be something else that's wrong?
I have also discovered that turning on the air conditioning keep the RPMs to stabilize, and the higher I turn the A/C, the more power it seems to get. Don't know if that is related.
I recently purchased a 2000 Durango with 151K on the clock. It looks like it was well taken care of, clean inside and out, and runs/drives nice. I just have 2 "concerns". There are times when the vehicles shifts from 1-2 and 2-3 it "shudders", only does it for a split second, and seems mainly when pulling out on some sort of upgrade, but not always. Otherwise it runs and shifts fine.
The second "concern" is that it seems to surge a little at idle. At a warm idle in park is when I noticed it. It goes from about 750 rpm to 950 rpm over and over. I haven't really noticed if it does it during regular driving.
My '96 Honda Accord has about 174,000 miles on it. Three weeks ago I checked my oil and the oil was black and way above the full level. I had also been adding 8-9 ounces of coolant previous to checking the level.
My coolant temp gauge has never gone beyond normal range. Two mechanics said I had a blown head gasket. I decided to change the oil and filter and only put in 4 quarts of oil. The level is only up about 1/4 inch level and the rest of the dipstick is completely clear. My friends also checked and it is so clean, like there is no oil in the car, but I have no signs of oil leaking. My oil pressure gauge shows normal pressure.
I continue to add 2-3 ounces of coolant each week. Early in the morning the engine shudders a minute or two before calming to a normal idle. I only drive around town a little, 75 miles a week. Can I continue running the car in this condition? If so, for how long? There is nothing else wrong with the car. Is it worth repairing?
During the winter, i always noticed that when starting up the car for the first time, the rpm always jumped high for about 60sec - probably around 1100. i know is normal - just the antichoke kicking in. However, summer is almost here and today was a hot day, and when i started the car and it automatically idled at 600rpm straight away. Is this normal ? or has something happened to my autochoke?
View 8 RepliesSo my R32 idles high when stopped and I googled it and people said that a new battery fixed the issue. I replaced the battery and it stopped doing it for a few days. Went on a long road trip (1200 miles) and it did it again. Been a few months still does it.
View 24 RepliesCar started to do some weird stuff today. Misfiring under high load, as I get into boost.
Idle is around 1000-1100 RPMs. Cold start is fine, idle is normal in terms of going higher a bit, but then it sits at 1kish. This started last night after the car sat for a couple hours. Totally normal running and driving prior to this.
I've seen all the MKV threads about it that suggest everything from battery, to alternator, to grounds, to vacuum leaks, to intake leaks, to MAF.
My car is a 2010 gti mk6, unitronic stage 2, apr turboback, r8 coilpacks, stock intake with k&n drop in filter. Several months ago, it started throwing CELs, P2096 post catalyst fuel trim system too lean bank1. I cleared it. It kept coming back. Sometimes it threw P2293 fuel pressure regulator 2 performance but I read it via VCDS, it should be P0088 Fuel Rail/System Pressure too high - intermittent. it was accompanied by some high idles at stop light e.g. at constant 900, 1000 or even 1200rpm occasionally. but the car drove well, seemed like nothing wrong.
High idle youtube link: [URL] .....
I changed the front o2 sensor but the problem persisted. Then I thought it was the MAF, I unplugged it, oil consumption improved but high idle and the above P2293 persisted. Recently, the high idle appears more frequently. I now suspect it is the PCV valve. I took off the oil cap this morning, felt some suction, the engine shakes a little and exhaust sounded a little rough but rpm didn't change. Taking off the oil dipstick showed the same. Is it the pcv valve?
On my 2010 Golf with 2.5, when I first start car above 40 degrees it goes into high idle for a few seconds which is normal. However, below 40 degrees it goes into low idle on cold motor. I brought this to 2 different dealers and they checked computer and fin no fault codes. How can I get this fixed?
View 11 RepliesYesterday when I started my car the coolant temp was near 100 (from a previous drive several hours prior) and it was over 80 degrees outside, yet the car went into high idle mode as though it was cold outside. It does this sometimes, but not always, and if I dont let it idle down and just start driving, it'll stay in high idle for a long time (i.e. even after a couple miles of driving, if I put it in neutral it'll rev back up to high idle).
Air temp sensor and coolant temp sensor are working properly, but it doesn't seem like a normal thing to do, but its done it for years. Anything else that might cause it, or any way to stop it?
I have a 2004 Malibu Classic well maintained 2.2 L engine 20k miles. When the engine is warm in drive at idle, the engine shudders vibrates the dash and steering wheel. It idles smooth when cold. In drive it settles to a base idle about 575-600 RPM. When I raise the RPM with the peddle just a bit maybe 50 RPM it idles perfect. Otherwise the engine runs perfect, air cleaner and plugs are like new. Is there any way to adjust the idle up or identify what sensor controls the idle?
