So i'm dealing with an 04 STI. Check engine codes appears to be...
p0011-Canshaft sensor bank 1 over advance timing
p301-cylinder 1 misfire
p303-cylinder 3 misfire
I replaced my sparkplugs 2 weeks prior to this problem with ngk 7 series plugs.
Checked all my coils by unpluging the harness to each one. I even replaced 2 of them on the passenger side which "should" be cylinder 1 and 3...still have the problem. Bought 1 brand new cam shaft position sensor and replaced the passengerside, and still misfiring...even switched the new sensor to the other side on the driverside to see if it was the other side of my motor...still doesnt work. Sea foamed my engine to see if my injectors would clean out...I'm out of ideas and im hoping its not bent valves cause
Before the problem, I only smashed my car to 4,500 rpm from 1st to second to third. I was a little low on oil about 2 qts. that day
NEed HELP!! PLZ
