So today when I started my car that my brother left parked on the street. All I did was reverse park it back on my drive way and I noticed it making a weird sound.

Rpms bounce and the air/fuel ratio goes nuts. It's supercharged.

anyone?

 

Just a guess, but did you look into checking the IAC valve?

 

Yeah, is the IAC valve. Is that the one thats on the back of the manifold? If it is I would take that off and give it a good spray with some carburator cleaner. I had the same problem and it was a simple fix... It can get dirty with intake deposits and cause a bad idle...

 

I get 1100 rpms when I unplug my TPS. Just a thought...

 

check the tps

 

x3 on the IACV, it's really easy to clean, will take you probably 5 minutes to get it off. If that's not it, your tps might need to be adjusted.
