Hey all,
Ive been having some codes being thrown quite often (P0172, P0175, P1431, P0300). I inspected the engine and found nothing wrong, no fuel injector wire chaffing or anything. I pulled the plugs and this is what I found. I did not pull plug from cylinders 5 or 8 for time sake. Please take note of the insulator color on plug 7. I put a scanner on the car and it said cylinder 7 was misfiring. Knowing the codes and seeing the plugs, anyone got an educated guess or know something else I could check or look up?
