Are the spark plugs one of the parts you changed out ? How about the fuel filter was that changed also ?


May also want to add some fuel injector cleaner to gas tank.

Plugs, wires, rotor, cap all changed egr valve, idle control, coolant sensor all have been changed,fuel filter is tomorrows project, and to check fuel pressure,,,

Fuel filter ain't problem either
