Alright guys... the v6 project Im working on for my wife has a little glitch. Problem is when you first turn it on it has slight hesitation when you give it throttle. Sometimes it backfires as well but not very often. But when the car gets to normal running temp it pretty much clears up. Anyone had this happen to there cars? Is it a timing issue? Let me know what you guys think.
