I give up. What is your car's model year?

Assuming this is a late model, the DTC is DIRECTLY related to a missing cam sensor. Do not continue to drive the car with this DTC. The fuel injector will fire on every stock. This results in twice as much fuel being sparyed. It will wash the oil off of the pistons and may damage the motor.

P1309 - Misfire Monitor Disabled When the misfire monitor is disabled, usually due to the input signal generated by the camshaft position (CMP) sensor, by sensing the passage of teeth from the CMP wheel.

2003 GT Convertible (sold & missed)
2000 GT coupe (Craigslist project. Fixed. Now my DD). Windsor to Romeo swap.
