I have a 1999 Pontiac Grand Am and everytime that I come to a stop my car dies but it starts right back up. It happens every time that I let the RPM drop so when I stop I have to keep the RPM up to 1000 so that it wont die on me I have taken it to get checked out. One place told me that I needed to change out my fule pump and filter so I did but my car still dies on me then I took it to another place and thay told me it was because of my battery so I bought another battery another place told me that its my ECM Computer but I really dont want to pay all that money if thats not the problem so is there anyway that you can tell me whats going on with my car I really would like to know whats going on with it.

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.
