2003 Hyundai Tiburon 6 cyl Front Wheel Drive Manual 70000 miles
My son recently put headers on his car. Also had the clutch and flywheel professionally replaced. Since the clutch repair, the check engine has come on and the error codes as read by the mechanic are P0122, P1505, and P1507. The catalytic converter has not been reinstalled yet (since the headers were installed.) Could these error codes and the engine light be caused by the headers? The plan at this point is to take the headers off and reinstall the exhaust manifold, will this possibly fix the problem? Are these errors something I could fix myself with a repair manual?
