i HAVE A FORD EXPEDITION THAT RUNS KIND OF ROUGH AND SEEMS TO BE FUEL RELATED, COULD IT BE A COIL PACK, EVEN THOU i'M NOT GETTING ANY ENGINE CODES?
RUNS KIND OF ROUGH WHEN DRIVING, BUT ITS INTERMEDIATE, AND IT
IS NOT THROWING ANY ENGINE CODES YET. LAST TIME THIS
HAPPENED, IT WAS A COIL PACK, BUT, THIS TIME AROUND, I AM
GETTING NO ENGINE CODES.
