HOW TO CHANGE PLUGS IN 5.4??
Big decrease in mileage. Do you think my new FQR has the plugs from my old 5.4? If so, the plugs have 58K on them.
I know where the plugs are. Under the coils. Is there a secret to changing them?
Anything I should watch for?
Could it be that my O2 sensors are bad?
Any help appreciated!
