Could this be my problem??

I just read the sticky aboutt he AIV repair/removal. It sounds like this could help me out with my problem.

Basically, I've got a bad idle and car rumbles ( on idle ) anywhere from near stall to 2K RPM's, BUT, since the weather has gotten colder it idles steadly at 1000 RPM with no notices of rumbling. Now the weather has gotten back over 11 degrees celsuis and I seem to be having this problem again.

Now, i know for a fact that there is also some vacuum issues with the car, I tested vacuum near my EGR valve but the valve is not malfunctioning, but vacuum could be better.

Again, the weird thing is that it does improve with colder weather, is this because colder weather is denser and can get by the gunk??? I know that it probably does not hurt to try it, but for those that did it, did you have the same symptoms as I did???

Also, I know the engine is strong and that is not the culprit.

Thanks for the help.

clean your throttle body and reset base idle .

also check your coolant temp sensor connections

take out the AIV, it fixed my problems.

Cool thanks, I'll do this as well. I already did the Throttle Body cleaning and it did help a ton.
