2002 Toyota Camry 205000 miles
Engine seems to run fine but you can hear a slight up and down rpm, very faint sound. When you excelerate it feels like your riding over a small wave. I changed all spark plugs to iridium, new fuel injectors, new ignition coils and replaced plug on cylinder 3 ignition coil. Engine light will not go away and get p0303. Seems like coil is not communicating with ECU. I get p0172 as well but replaced MAP and up/down o2 sensors..HELP! Btw my cylinder 3 coil burn out twice in the past, it must be an electrical problem
