missfire??? I jus dropped in a freashly built LS! with heads and cam. Car has full bolton and so on. The motor keeps misfireing and a small amount of smoke is comming out of the exhaust. We have tried messing with it and fixing it with HP tuners. Another thing, my tach is not working. I already swaped out the cam sensor twice and nothing yet. Were thinking it might be the cranke position sensor that causeing all this? We have already swapped plugs, wires, & coils but nothing. Also, the map sensor was swapped twice also cause it reads wot when the car is off or idle? Any help please?
