My car is reving on its own as if I'm blipping throttle, but I'm not.
It all started when I up graded the intercooler?
sometimes it runs and idles perfectly fine and then there is times when it just starts reving by itself from 750 to 2500 rpms and then drops back to 750.

any ideas

thanks

 

Not sure, but make sure all the hoses are tight.

 

Yeah i had this same problem with a few of the cars i have owned, It is most likely a vacuum leak, check all gaskets and hoses that you changed or touched when you installed your intercooler and make sure they arent leaking, reused gaskets tend to leak but im not sure if you did or did not reuse one.

 

Are you running an APEX'i PFC?

 

Check the little pin on ur Throttle body. If it backed out it would do that. Mine did that just not that bad

 

you think you got problems. my car drives itself.

maybe it has something to do with your screen name

 

haha the last 3 posts are funny.
how does it drive itself? most cars do, i dont mean that literally i mean that like they ride nice and if you drive a cadillac you know what i mean.

 

thanks for the help, I've not had the problem in the last 2 days but I'm going to check everything suggested.
thanks for the laughs too. good posts

 

Could have knocked the TPS also.. although if you were doing an intercooler you weren't really working near the TPS..
