2009 Ford F-150 XLT CrewCab 4.6V8 3V...continuing failure of coil packs
Made it to 214k miles before replacing all plugs and coil packs in March 2018 due to the bucking/kicking at 40-50mph...ran great for a few months, then three of the new coil packs went bad. Shop replaced them under warranty. Then #6 croaked about a month after that. Shop again warranty replaced. Went bad a third time now, plus at least two more have joined the party, will have to take it in on Monday. Idles rough, runs rough, not enough power to accelerate hard, gas mileage dropped from 19-20 to 9.3mpg.
