[QUOTE="Sorin W, post: 1018232, member: 70336"] I don't know if your issue happens only when the engine is still warm, that is my case. Mine will always start perfect in the morning or after a few hours after the truck was driven. Please check the discussion at the following link: http://www.twoguysgarage.com/forum/showthread.php?t=8434 The guy solved exactly the issue I'm having by replacing the coolant temperature sensor and TPS sensor, but he's almost certain to be the coolant temperature sensor that took care of the problem. Watch the guy in the youtube link below that explains why that sensor causes this problem, mainly because the temperature reading tells the ECU how much fuel to dump in the cylinder if its a cold or hot engine start.
