2000 5.4 Triton Problems Help!!!!
Hello Everyone. I am new here so any help would be greatly appreciated. I just bought a 2000 F-150 with the Triton 5.4. After a week of happy driving It started running real rough. I hooked it up to a computer and it gave me a cylinder 7 misfire code. I replaced the coilpack and a new plug. After that it started reading a cylinder 5 misfire. I replaced the Throttle pos. sensor because it was reading 19.2% at idle. None of this has helped. It has no power the check engine light is on all the time. HELP ME PLEASE!! Do I need to keep replacing coil packs until the problem goes away????
