i have an 1999 gmc sierra pickup 5.8 and it is shaking really bad and like hesitates when you go to like take off from a red light i have check the plugs good and the fuel pump and filter is new and i have tried the Lucas cleaner and still no luck any ideas?
i have done the plugs and i kno its not that and it is a multi coil and i kno what the code mean but just dont kno what all i should do first
