    CODE P0304 IS ENGINE MISSFIRE CYLNDER 4 AND P0354 IS FOR COIL D WHICH IS ALSO CYLNDER 4 YOU WILL NEED TO REPLACE THE COIL FOR CYLNDER 4 AND MAYBE SPARK PLUGS THEY ARE DUE TO BE CHANGED AT 120,000 BUT COIL SHOULD FIX THE PRIMARY CONCERN AT THIS TIME

    Thank you!! Not sure of firing order but think cylinder 4 is if I'm standing facing the hood I see 3 coils in front which is actually the side, and number 4 would be in the center?? How do I clear check engine light or will it go off by itself once I replace coil and plug? Do I determine left side, right side from sitting in the car or standing in front? Facing the car I see belts to the left side, which would be the front of my engine. I'm used to Old School Chevy, not front wheel drive. Again Thank You!!!! I asked on a few sites and you are the only one to reply!!!!
