I have a misfire every time the engine get to op temp change the spark plugs. The only cel light that’s on is for the secondary o2 needs a bung welded on. I just rebuilt the motor and I believe the timing is fine but I can’t adjust ignition timing because the p5m ecu does it for me. I have all stock components beside the short block internals are all forged and the compression is now 9:1 because I’m looking to turbo once I clear up these problems. When I rev it the rpm’s just around like crazy and it won’t go past 3,000 rpm but when cold it’s just fine. I’ve sprayed carb cleaner around the intake no changes idk what to do.
