View Full Version : Idle messed up again.

so I finally thought my idle problem was fixed but now the same problem is going on. For some reason only when in park or neutral the idle just jumps up and goes down then goes up a little more. It's usually in between 1100 and almost 2000 RPM. I have already checked my vacuum hoses and I just recently changed my EGR valve becuase the Engine Check Light was showing a code 71. I also timed it like two weeks ago and right after that the idle was holding perfectely at 800 900 RPM but for some reason not anymore.

Any Ideas of what it might be?

Double check your vacuum lines again. 90% of the time it's a vacuum leak. :)

so I was looking around in the engine bay for a vacuum leak or something and I noticed that my Idle mixture screw is screwed all the way out which I'm pretty sure isn't a good thing.

Oh and I have another question would a vacuum leak kill your gas mileage?
