1996 idle relearn?

remove the IAC, take and clean out its' port with carb cleaner and a tooth brush/bottle brush, etc, and reinstall. make sure you don;t loose the O-ring.

unhook battery to reset everything, (negative terminal!) Once you are ready to start it back up, turn the key to run without starting the engine and wait ten seconds before starting, the pcm will run the IAC through it's travel to relearn it.

It's plenty clean, thanks though.

 

 

I wish GM just used one method across all product lines/years :think: I've seen about 6 different methods of idle relearn so far.

 

thanks again!
