Re: poor idle

Reset the iac. go to shbox.com for directions on how to do it I would also check for compression, clean the throttle body, and clean the maf sensor with electric parts cleaner.

Re: poor idle

Check your vacuum lines. I put in headers and tried to fire it up without blocking the EGR holes in the back of the intake and had a similar problems. I also had a cracked vacuum hose later and had a bad idle.
