Passat (B6) :: 2008 - When A/C On Idle Rev To 1900 Rpm?
Sep 12, 2011
I bought my 08 TSI in January with 23k and shes now at 34k and its been a fantastic car. I got my second oil change done last week and after a little roadtrip, I put it in park with the AC still on and the engine alternated between regular idle of 600-800 rpm to about 1900 rpm. This was resolved by turning off the AC but I don't remember this happening in the past and it doesn't seem like a healthy symptom. The car is still under warranty so I'll probably take it in for a look. Nearly 2000 rpm to keep the compressor powered up is really excessive right....

When I start my car now, it will idle up to about 1900 rpm, then idle down from there (even when engine is warm!). Also, I drove about 30 minutes, and a guy in a lancer decided he wanted to race me, but it seemed like I wasn't getting all the power I should! I tested this theory in an empty parking lot, where I found that my tires wouldn't brake free even at high RPM with stage1. This has never happened before, and I am a little worried at this point. My mod list is in my cig below in case your wondering, of if that makes a difference. What should I look for.

I just purchased a 2008 passat, 2.0T 6spd manual last night and I noticed today, when sitting at a stop sign it has slight idle issues, (goes up about 200-400rpms) then back down to normal idle. Doesn't seem to be causing any issues, its just pretty annoying, and everyone next to me thinks I'm trying to race them.

1st - Handbrake fault warning on the dash (only comes on in really bad wet weather?)
2nd - Owl Hoot when changing gear

So, I have heard a little bit about the oil pump bolt issue. However, I am still confused. Was this issue fixed for the 2008 model and what are the symptoms? I changed out my valve cover last night due to a PCV valve failure. The car is running great except there is a slight rattling sound coming from the drivers side of the engine at idle. I know I left nothing around the car that could have gotten in the motor when the valve cover was off. This issue was not happening before changing the valve cover. What could be causing this noise, or is it typical for this motor?

My 04 V6 start-up RPM has jumped from about 1400 to 1900. Haven't performed any maintenance that would affect RPM at start up. MAP was cleaned with CRC product made for this procedure and a new MAP o-ring was used. Throttle body control valve is clean and shows no signs of residue build up. I have lifted the negative battery terminal for an hour with no effect. Haven't found a vacuum leak. Only thing that has changed is use of Shell gasoline. Throttle pedal was replaced last October ,but start-up RPM did not change until June of this year.

I recently purchased a 2003 jetta 1.8t 5 speed manual and it wasn't making this noise when I first bought it.. It's almost like a growling/grinding noise. It's sounds like it's coming from my middle console but it could be coming from the engine bay hard to tell, but the only time this noise happens is at 1900 rpms when the car is under load like if I'm going a hill it's pretty loud when I'm going slow, the previous owner had the water pump, timing belt, and clutch done 10k miles ago. I have a feeling it's from the clutch/transmission or maybe from the timing belt?

I have no CEL at all, no loss of power etc..... but this rattle comes from what seems mid point under the car around 1900-2600 rpm in that area. I tapped on the Cat and there was no noise. Could it be from the mid point around the resonator ? I am really starting to get at a loss here about the sound. like I said No cel and performance is on par. if it was the honeycomb in my cat wouldn't i have a CEL ?

This was a problem with the first generation GX470. It was finally resolved.
I am experiencing this in my 2011 GX460. I would have thought this was engineered out of this vehicle by now.

Over the past month, my car has been hesitating in 3/4 gear right around the 1900-2200 RPM range. The tach moves up and down (like a rev limiter) between that RPM range for a few seconds then it is okay. I notice it mostly when I get on the expressway. The car has 185000 miles and here is a list of things that I have replaced along with the mileage that I think might possibly be the issue:
Mass Air Sensor -163000
Tune up - 160000 (Plugs + Wires)
Fuel Filter - 145000
I checked through the forums and didn't see my particular issue. Thoughts on the issue?
2001 Pontiac Grand Prix GT, 3/8L non supercharged.

I have a 96 f250 7.3 I just cut the cat and muffler, and developed a drone @ 1900 rpms. if I shift out of OD it goes away if I get to that rpm in OD it drones. What would be my best plan of attack to get rid of the drone? Hollow out the cat and re install?

I get what I can only describe as a "missing" when Im on the interstate just cruising along with rpms below say around 1900. That seems to be when I have noticed it. It is not very frequent but often enough to not let me forget about it. Happens when I'm towing it seems more than when not. Seems the rpms have to be below 18-1900 and in 5th speed. You can just feel the truck ever so slightly missing like in the old days of points and distributor caps. No tunes

When the engine is fully warmed up no heater on, after driving about 7-8 miles in city my engine would make a fluttering/tapping noise between 1900-2700rpm at 5-30mph during light acceleration. its rotational noise definitely from engine. noise is light, to hear it all windows has to be up. noise can be heard when powerbraking as well
i had taken it to hayward toyota, dublin toyota and fremont toyota total about 4-5 times. some would lie to my face saying they cant hear the noise, some would say its normal. i used to be a mechanic now im a service advisor at nissan. always had confident in toyota bought 2 of them at the end of 2013 before i started working at nissan.
I had my shopforeman looked at it couldnt figure it out. had my master tech looked at it couldnt figure it out. both informed me this has to be looked at by a toyota mechanic to see if this is an issue they had ran into before or call a toyota engineer.

I have a idle problem that happens on and off. with my 89 f250 351, it revs at 1900 rpm and when I unplug the vacuum hose to the map sensor it idles about 700 rpm. I've already replaced the map sensor and it does the same thing. i cant find any vacuum leaks anywhere and when i unplug the connector to the IAC nothing happens it continues to rev high.

I'm having a problem with my 2012 Mazda3 (automatic, non-skyactive model) that others seem to be complaining about on the online forums, but there seems to be no consensus.
About 10,000 miles into owning the car, it started making a sort of high-pitched gargling sound when I accelerate and the tachometer reads 1500-1900 RPMs. At first, the sound occurred sporadically when I was accelerating under these conditions, but now, at 28,000 miles, it's happening almost every time I accelerate between 1500-1900 RPMs. Here are a few more facts:
The engine must be warm. The car must be in drive (I cannot replicate it in neutral or park)The sound occurs regardless of whether the AC is on
I took it to the dealer 3 times. The first time, they changed the belt, and that worked for about 1000 miles. The second time, they told me that the noise is normal, and I should not worry. The third time, I took it to a different dealer, and they put a "dressing" on the belt. That worked for about 600 miles. Now the sound is back again, and it's driving me nuts. It definitely doesn't sound normal. If I test drove a car at 28,000 that made this sound, I definitely wouldn't buy it.

The video below IS NOT my truck, though my truck makes the same sound. Mine isn't nearly as loud as the truck in the video at idle, but gets much louder when under load at about 1700-1900 rpm. If you take it easy accelerating it doesn't get any louder than at idle. At cruising speed in third it isn't audible. The trans in my truck is a 1979 C6. Again, not my video. Same noise though.

I have a 2008 focus and at about 15000 miles started having a slight vibration at idle. Its idling at about 700rpm is that normal? It more annoying than anything. Took it to Ford and they just say its normal. What the problem could be? Should I replace the plugs?

Friend of mine drives a 2008 Camry with 2GR FE engine, with 65 000 miles. When the engine is cold it runs fine but when is fully warm it idles low, in D or R at around 560-600 rpm. When he shift from P to R or from N to D, the idle goes down, not up like it should. The spark plugs are new, air filter is new. No CEL.

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.

I have a 2008 Chevrolet with a V8 5.3 liter engine. When idle or at low speed the car shakes. When accelerating there is a drag. What could be the problem? And how can I resolve it?
