GT500 missfire?

This code comes up when you replace the battery, or disconnect it for an extended period of time. it is not goin to harm anything and normal driving will clear it after a while. the part that takes the longest to complete is the catalytic converter efficency monitor, which may require extended freeway driving.

If you want to clear the P1000 you have to Perform the Ford Motor Company Driving Cycle.
WTF? seriously that seems awful complicated just to clear a code lol
