The right bank of my car is running rough or cylinders 1-6. I have changed the spark plugs, wires, intake manifold gaskets, cap, rotor, and vacuum hoses. I have checked and cleaned the fuel regulators and throttle bodies. I have checked the mass air flow sensors, fuel pumps, and MOTRONICS. There is no check engine light. The car is starting in limp mode.
