Asked by GuruZ8CXS Dec 22, 2017 at 11:59 AM about the 1998 Ford F-150 Lariat 4WD Extended Cab Stepside SB

Question type: Maintenance & Repair

My 98 f 150 is gunning like my coils are misfiring but, it has
something to do with my harness that goes to the battery,
coils, alternator etc. What do you think? I can wiggle it at
time's, and it starts running fine but, lately it's been harder
to straighten out.

Those are bad about the spark burning a hole in the spark plug boot. This can not be seen in the dark. If it has a boatload of miles on it and the plug wires have not been changed that would be a good place to start.
