I'm new here and am in need of a little assistance. Two years ago my 5.4L 2002 F150 Super Crew hit 100,000 miles. I decided to keep the truck and started working on a plan to enhance and revive it. I'll just list what was changed and then get to the issue. Transmission kit, radiator flush, suspension bushing replacements, AirAid open intake kit, Iridium IR plugs, Granatelli Hot Street coil paks, FiveOMotorsport 21lb injectors, long tube headers with single Magnaflo exhaust. The truck ran great! Better than ever when new After a few months one of the coil paks failed. GMS replaced it free. At this time I have had five coil paks fail. That includes a spare OEM unit I bought to keep me going while I received replacements from GMS. Sure could use a little help with this one.

Thanks
