I may be in the same boat as you (now just to figure out what that boat is <img src="/forums/images/graemlins/notooth.gif" alt="" /> ). During a cold start, my truck starts just fine... but then stumbles and tries to die and I have to play with the throttle for appx. 30-60 seconds. After that, it runs/drives just fine and will continue to start and run fine until it has been sitting for a few hours. The only difference is that my idle is fine. Been working too much to check into it... but its getting worse so I need to find time <img src="/forums/images/graemlins/scared.gif" alt="" />
