When the truck sits for any length of time it has a hard time starting and chugs when it first starts. Then it runs great except on low idle when warming up. it starts great if sits for short period. Someone suggest Lucas ejector cleaners, have heard fuel filter etc. HELP!!!i am a woodworker not a mechanic

honestly, it could be as simple as a dead cell in ur battery. or well have a cell going bad, sounds like its drainin slow and not holdin the charge up, but then the alternator is kickin it back up when u start it. but thats just a guess at the most simple reason.
