i have a 2003 chevy Z71 1500 5.3 with 175000, it will crank and will run but when i stop it will not idle can you guys give me an idea where i should start to get this problem fixed.

thanks for the info

First inspect carefully for any vacuum leaks and repair them. Once you have done that, you may have a bad IAC ( idle air control) but try cleaning the throttle body first. Remove the intake snorkel, have someone hold the throttle wide open for you and scrub the back side of the throttle plate and surrounding bore with an old tooth brush and some carb cleaner. Be sure to spray some into the small holes next to the throttle plate. That should help stabilize the idle. If it still has a problem, replace the IAC.
