i'm just driving along, come to a stop light and i shift into neutral, but my idle stays at 2k. i was like wtf... so the next light i come to it does the same thing. but then the third light it went back to normal - around 850. this happens just about everyday - although not consistently... one time it'll be fine and the next time it'll go to 2000 again. this happen to anyone before? anyone know how to fix this? thanx.

 

all i know is if the idle jumps around when you are at a stop then it's the o2 sensor. your throtle might be sticking open.

 

within the last few weeks. It covers this problem.
