Unpopular opinion: new coil packs aren't always the fix
Just had a misfire on a 2015 F-150 last Tuesday. Swapped all 8 coil packs and it still ran rough. Turned out it was a corroded ground wire under the battery tray, wasted $320 on parts I didn't need. Any other guys here actually check wiring before throwing parts at it?

Yeah, ended up being a loose ground strap on mine too.

Do you think it was from the factory or road vibration?
