My brother came in with an engine check light on, engine was misfiring at idle, put the scanner on got a code "P0301 cylinder 1 misfiring". Swapped the spark plugs from cylinder 1 and 2 no fix, but found cylinder 1 plug to be a bit wet a small smell of fuel, check the wiring all looks good. Guessing the coil pack is faulty, cannot swap the coil around since it's a pack. Is there a continuity test or resistance check that can be done with a multimeter to confirm the coil pack is faulty? Try to listen for any vacuum leaks didn't hear anything. Should a cylinder 1 compression test be done? Should I be swapping fuel injectors 1 and 2 also?
