2002 Ford F-150 King Ranch 4.6L Misfire
My question is why would these coils fail for a third time? Customer states both coils have been replaced two times before this repair. Failures are specific at cylinders 3/4. I use a Rotunda IDS and koer test passed, power balance looks good and all fuel trim...
