WIPER SWITCH – Remove & Replace
CLIFF G. gave our service a 5 star review on 8/30/2024
Had code p0301. Swapped coil to number 2 and spark plug with 5. Missing now on 2 and 5. Slight miss on 1. Not sure if miss on 1 is real. Recommend replacing 1 coil and all spark plugs and retest. May need 2 coils.
Change oil and filter. Inspect and top off fluids. Check for grease fittings.
