Idle misfire 6.2L
Has anyone encountered a misfire at idle after a drive over 40 miles? The engine is running cool ,but when I come to a stop I feel a mis fire or hesitation. I recently changed the plugs and wires for the problem but did not correct . Maybe I am overly concerned, the car runs fine at speeds above idle just wanted to know if anyone else experienced any thing like this. The engine only has 15000 miles on it.Bought it used with 13000 on it. Maybe its a 6.2l thing Does anyone know what lift cam they put in LS3 Grand sport 2013?
