I know this really doesnt belong here but people that read the PCM section do not like to answer posts unless it pertains to "real" tuning issues.

My car had a difficult time starting. It acted like an old sbc with a holley and not coke so i changed my IAC. The car now starts normaly but the idle is high (about 1000) and the motor decelerates slowly. Any ideas on what i need to do to fix it.

Make sure the orange o-ring is still on the IAC and if it is make sure its still good and not tore or pinched.

 

its there. This isnt one of those parts that you have to retune for is it?

 

Nope.

Are you sure it was the IAC that was actually bad in the first place? Maybe try putting the old one back in and see if it goes back to how it was, or just still has the high & hanging idle. That'd be the next thing I'd try, just to eliminate that possibile variable.

 

how long since you've changed the IAC?
How many miles have you driven?

 

2 days 0 miles

 

Drive around and give it a little time. I bet the it will work itself out. When I put on my new tb it took a while for the new IAC to find the idle. I drove around with it and after a day it was fine.

 

Cool, ill take it for a ride this weekend. Thanks

 

same here. It took three dyas before it settled down. You might also want to make sure you have no air leaks around the bellows.
