Golf V R32 :: Strange Idle When Stopping Or Sitting At A Red Light
Jun 25, 2008
I started noticing a strange idle when stopping or sitting at a red light. Upon stopping the car idles at around 600, then all of a sudden it jumps to around 1000-1100, and sits there as if I was giving it gas. As I drive off the car drives fine, once I stop again, the same thing repeats. This happen to me 2-3 times already within the past month, I mostly drive on the highway, so that might be a reason I don't notice it often.

So far I have only experienced this once (today). I was on the freeway which ends and becomes a State Route. When I stopped for a traffic light the idle became rough. I put the car in neutral and gave it a little gas and it seemed fine. It has not done that again at this time. No CEL or anything came on. What do you think?

Today I should make trade for MKIV R32 and I only thing I'm bit worried is this one sound. It appears when speed is over 40 mph/60 kmh. And especially then when I set my gas pedal loose / idle. The sound seems to be coming from back and it reminds the sound when you leave your window just little open and wind blows in making very similar sound. It is high frequency sound and not loud but still can clearly be heard. Almost like whistling type of sound. Then when speed decreases below 40 mph the sound disappears.
The car has milltek resonated exhaust.
Only thing I could think of is that if there could be some hole in exhaust pipe or in window caulk/seal..

So my rpm bounces at idle and there is a strange whining sound which seems to be in unison with the peak of the rpm bounce.. and it all stops when the heat or a/c is off.

When my R32 is sitting at idle with the A/C on, I occasionally get what I can only describe as a high frequency "hum" or "moan". I've tracked the noise down to what looks like a sensor or valve on the A/C system, located in the rear of the engine compartment near the left (passenger) shock tower. Turing the A/C off, blipping the throttle, or putting the A/C in "ECON" mode will make the noise go away for the most part.
Is this the thermal expansion valve? And what the heck is causing the noise? Faulty TPV? Or low A/C refrigerant charge? It's annoying as heck and scares the crap out of people near the car.

What would cause and how to fix my Jetta. It will idle at almost 10 rpm sitting still? It also sputters as if trying to die. It has an after market air intake with a ktm air filter

I have a 2012 Elantra that I bought used with 15,000 miles on it. Since the day I bought it I have had different issues with it but one of my huge issues is that when in idle at a light or sitting still anywhere my car shakes like someone is bouncing a basketball in it. I have taken it to the dealership multiple times and they have replaced PCV Valve and cleaned it before replacing it and they have done some other things as well to it. I have gone to just talking to the service manager every time I go to service because I have taken my car in for the same issue every time!! I usually wait til there are multiple reason to go to the dealership before I take it back in because they never fix the issue!!

I have a 04 jetta 1.8t that just randomly started having some overheating issues. I just got the car two days ago, and the first day I had it I replaces the coolant temp sensor due to a check engine light. Drove 50 miles and the light shut off. Just yesterday I was sitting in traffic and noticed the temp going above 190 (which it hadn't done in the 200 miles id driven it so far). I brought it home and once I was out of traffic and moving along the temp went right back down to 190. The only time it tries to overheat is when its sitting still or at idle (after reaching operating temp). which is weird.
I was parked in my driveway and let it sit at idle for a few minutes until the temp started significantly rising. i revved it to 2000 rpm (thinking it would rise even more), but to my surprise it instantly went down to 190 again. my big fan isnt running either, but my friend said he doesn't run fans in his and that it shouldn't overheat because of the fan. also, my top hose is warm to the touch, but the bottom isn't. I know your thinking thermostat, but if that was the problem it would :
1: always overheat, or
2: never overheat.
The temp wouldn't fluctuate the way it is.

About two days ago a noise started happening when I sit at idle... The moment I touch the throttle it goes away. It's rather loud and disconcerting.
The video starts off in drivers seat, then I took the phone to where the vent for the defrost is, and then below the glove box. It's audible everywhere.

When my Camry is in DRIVE and sitting at a red light for example, my car will shake. It feels like it idles rough. If I put it in neutral the shaking goes away... only when in drive.
I took it to Firestone who mentioned I had a dirty throttle body. So I get this cleaned and the shaking has significantly reduced. However after a few months I'm back at square one. Dirty throttle body and care is shaking again. (Yes air filter is clean)
I noticed two things that I think might be contributing... After 5,000 miles my oil is pretty black and very low. (Time for an oil change) When I swipe my finger on the exhaust pipe, its really black but no black smoke comes out. I don't see any oil leaks outside of the engine, its actually pretty clean.
So two questions, is the low oil and black exhaust pipe normal? Why would my throttle body keep getting dirty?

I have a 2001 Mazda Tribute with 150,000 miles that is meticulously maintained. This past winter (as far as winter goes in San Diego) the engine would run rough and the rpm's would drop close to stalling when stopping at a light for the first 2 or 3 miles. After that the engine has warmed and there is no problem. Could this be the intake gaskets needing replacement. This only happens on a cool or damp, rainly morning.

I have a 95 honda accord 2.2L, 135,000 miles. One day while sitting at a light the car started vibrating due to a rough idle problem. The idle speed is ok at about 750 rpm.

I have a 2016 F-350 with the 6.7L diesel in it. Truck has 10,000 miles on it now.
Since about 3 days now it's giving me grief at idle, e.g. sitting at a red light. The idle is very inconsistent, I can see it on the gauge and you can also hear it rev up then slow down. When the idle rpms drop down (below the 500rpm mark) the whole truck shakes for a second then the rpms come back up. then drop down, back up,... and so on. It does it regardless of gear, it's more pronounced even in P or N.

So i've had the car for what, maybe 16 months now and tonight while the wipers were on s l o w speed, I came to a full stop at a light and the wipers stopped wiping, and then either went into intermittent or rain sensing mode. When I started moving again the wipers starting wiping continuously again. Never knew we had this functionality.
I have to admit I've been a fan of the rain sensing feature and just about never use the low or high speed settings except maybe when it's constantly raining on the freeway. So I guess tonight must have been the first time I've used the low setting while in town and had to make a full stop.

I recently bought a used 2003 jetta wagon with 159k. Is it normal to feel and hear a growling sound when the air cond is running and you stop for a red light. It's a 2.0 automatic jetta wagon. I never had a 4 cylinder automatic car and this is my first VW.

I have an 03 vw Jetta 1.8t with around 100,000 miles and I recently ran into a problem with the car jolting, or slipping when I get on it hard. And also when I'm sitting at a stop light it will jerk forward like it wants to go. I've tried a few things like cv axels and some other things but I'm just hoping it's not the tranny.

I've had my ISF for about 3 to 4 months. I absolutely love the car and i haven't seen too many of them in this area (central NJ). I wonder why lexus hasn't done a better job of informing the public. Most people don't even know that lexus makes a V8 sports car.
When the car is on idle, there is this strange vibration that i feel coming from under the seat. It happens for a few seconds and then stops and starts again when the car is on idle. It happens when the car is not warmed up, but also when the car is properly warmed up. I'm not sure if its a cause for concern. Is it because of the timing belt? Engine? Just want to make sure its normal and have the car looked at if its not.

Lately or maybe I never really paid attention to it, there's this strange noise at idle. 2009 passat w/ 35k mi(auto trans). Noise sounds like a small dog growling or a swarm of bees. Doesn't always make the noise but sometimes when I come to a stop light or pull into my driveway I can hear. Sometimes the noise is constant or it cuts in and out. Pooped the hood and it sounds like it is between the back of the engine and fire wall.

Allright, I seem to be having these very strange sounds at idle. Mostly when I am in Drive and waiting at a red light. In Park, it isn't as bad it seems.
One sound is knocking. A kinda slow one and irregular. Not a motor knock tho. Doesn't sound like that. It also kinda clicks from under. So, those both sounds come from under or the sides of the truck.
Should I worry about this? I've had these sounds since I've got the truck. Sometimes louder than usuall.

'04 Honda Civic-1.7LFirst the car started overheating only it was sitting in idle. As soon as you would go or if you revved the engine the needle would immediately drop after a few seconds. Replaced the thermostat. It seemed fixed, but started doing it again, put in a new thermostat incase other one was faulty. Still having same problem.The system was pressure testing and everything was fine. Then had the system flushed and new thermostat put in. It worked for about 150 miles and started doing the same thing.Brought it in for the water pump, the old one was corroded and warped so it seemed like the problem.
After about 100 or so miles still overheating when idle.We had the radiator replaced, the old one was complete junk, thermostat replaced too. I drove it like normal in town for a day, the next day it started overheating, this time it was doing it while driving, got to about 3/4 up. Turned the car off for a bit, and it didn't do it anymore on the way home.Today I was driving and it was fine for 4 miles, I sat idling for 1 minute, after driving 1 more mile it started overheating, temp gauge got to halfway.
I parked it for a bit and started driving, there was no heat coming from the heater, I had it full blast, nothing but cold air. The car started overheating again, once again halfway. Parked for about 3 minutes and then turned it on, temp was fine and it was blowing full heat out, the car temp was fine the whole way home, no more overheating.
The next step we will take is to replace the head gasket and/or heater core. Is there anything else that this could be? Literally the same week the overheating started, the rear lights were having issues and one time there was no power to the windows. Then the door locks would stop and then work again intermittently. The door locks no longer work at all. Not sure if it is just a coincidence, maybe everything is breaking at once. But there has been no loss of coolant and the oil and coolant consistency have been normal too.

09 Ford Fusion, 5-sd manual, 37k. For the past week or so I've noticed after exiting the highway and stopping at the bottom of the ramp the engine will idle high. When I shift into neutral to wait at the light it idles at about 1,500 - 1,800 rpm. I will slowly drop to about 1,000 rpm and quickly drop from that to 750 rpm which is the normal idle. When getting off the ramp yesterday I put it in neutral while coasting and not touching the gas pedal, clutch or anything, the idle went from 1,500 to 2,000 rpm. Driving around town it seems normal, and the car drives normally with no issues on the highway up until I stop. What could be causing the weird idle issue?
