2010 Ford F-150 5.4 3valve did a tuneup changed sparkplugs and coils with correct Motorcraft plugs and AC Delco COP’s now I have burned off 2 ground electrodes in less than 100 miles. No codes on the computer or mis-fire information from my code reader. Used di-electric lube on COP boots and nickel anti-seize on the threads. Should I go back to the original Ford COP’s? I’ll have to add the image later as the one I have is too large of a file.
