A Little Missfire Help Plz.
My trans am seems to missfire or hesitate a little bit when driving before the engine is warmed up. Once the engine is warmed up it runs smooth as can be. Any ideas? It has new plugs, wires, optispark, fuel pump, LT headers, and dual exhaust. It isn't tuned yet and does throw the egr code. Any help is appreciated.
