P0303 cylinder 3 misfire. Swapped cylinder 3 plug and coil to front of engine. compression check cylinder 3 and 6 checked good. no change to misfire on cylinder 3. Added supplemental fuel and misfire goes away. verified injector #3 signal good. Recommend new injector number 3. (Replaced injector no more misfire)
Lubricate and check chassis. Change oil and oil filter. Perform 29 pt inspection.
THE SYSTEM HAD TWO CODES ONE FOR LEAN BANK ONE AND A OLDER CODE FOR SAME THING. WHEN RUNNING THE CAR WE COULD FEEL A MISS FIRE. TESTED THE SYSTEM AND FOUND THAT CYLINDER ONE WAS MISSING. WE TESTED THE SYSTEM AND FOUND THE COIL ON CYLINDER ONE NEEDS REPLACED.
IGNITION COIL – Remove & Replace – One
