Default Revs to the moon when I start engine.

Well not quite, but 2500 to 3 grand everytime I start it. It doesn't stay there long but kind of annoying.

I have cleaned the TB and IAC out, that helped with the stalling awhile back. Could bad O2 sensors be doing this? Or dirty intake, after the TB?

i'm pretty sure it just shoots up then comes down because in every car i've been in it's done it


are you saying that it stays there for like...5 seconds?

A friends neon started and never went over a grand, I just compared mine to his. But, it sounds as though his was the acting up one lol

Thanks for the replies!
