99 Black Bird T/A

iTrader: (4)

Friend has a low oil light he can't get rid of. The dipstick shows it's full. The oil sending unit/sensor has been changed out.

The car is also tossing a misfire code. Engine is stock. Car has headers and basic bolt on's. Didn't see any burned wires.

Any idea on stuff I can tell him to look for or check?

Thanks
