This is my first post on this thread and i got one problem. When I start my car up in the morning or anytime it hasnt been driven in a few hours, I turn it on it idles at about 2500 waits a few seconds goes down to about five hundred bounces back up then the car shuts off any help would be great thanks

 

ok, the 2500 is the auto warm up - thats hiding your underlying problem.
search for the 'idle adjustment' procedure and adjust it up - may solve your issue.
