I PERFORMED A VALVE JOB AFTER AN OVERHEAT CAUSED A HEAD GASKET LEAK. EVERYTHING WENT WELL, CAMS LINEUP, ALL IS WELL EXCEPT RICH FUEL SUPPLY ON START AND AFTER WARMED-UP. SO RICH IT WILL BARLY IDLE AND OF COURS FOULS PLUGS. WILL RUN AT HIGH SPEED BUT NOT LOWER SPEEDS. ALL GROUNDS ARE GOOD, THE READOUT IS 52 KNOCK SENSOR. HOWEVER 4 CYLS. DON'T HAVE KNOCK SENSOR. NO OTHER CODES PRESENT EXCEPT OBVIOUS OVER FUELING RELATED EMISSION WARNINGS. OBD-1 SYSTEM. SPARK IS STRONG, COMPRESSION IS GOOD, FUEL IS FRESH TPS IS WITHIN LIMITS, O2 SENSORS OK JUST DIRTY FROM EXCESS FUEL. CAN'T FIGURE IT OUT.

Hi there,

Thank you for the donation.

Check that the cold start injector is not leaking. Do a fuel rail pressure test to show any main injector leaks. Make sure that the ignition timing is set with the ECU in check mode & the valve timing is set correctly. Start here,
