What's up, guys? New to the forums. Picked up a 2001 Bullitt not too long ago.

Started having problems with the idle. When I turn on the car it's fine but as soon as I put it in gear and start driving it, it starts idling high at around 2k but it jumps up and down sometimes going as high as 3k rpm and sometimes it goes back to normal.

Somebody suggested that I clean the IAC and that's what I did but that didn't do anything. Should I just try replacing it altogether? Or could there be something else wrong with the car?

IAC needs cleaning or most likely, replaced. I had similar issues and this fixed my problem. Should do the PCV valve while your at it too.
