I have a 2004 F-150 that has spit two spark plugs out with in a year. The second one caught fire. There has been this issue with many owners of Ford trucks and is a on going issue Ford won't take care of. Napa auto parts has a repair kit made just for this issue with Ford engines. The cost is $ $73 plus having someone do the repair.

F-150 - 2004 Ford. Experiencing two mechanical issues. The most concerting is the fuel fumes/toxic smell that enters the cab. Secondary is engine knock. The vehicle's warranty expires in approx. 5K miles. Vehicle has been diagnosed and odor confirmed, however, no trouble code was given, therefore, Ford dealership can't make repairs without approval of Ford, who won't approve without valid trouble codes. The fumes are toxic and must be hazardous to the health of our family.

I just bought a brand new 2004 F150 4.6 L 4X4 super cab on January 31, 2004. Upon acceleration there is a noticeable jingling/rattling noise coming from the engine area. I have taken the truck back to the dealership service department 4 times and have talked to Ford customer service department numerous times. They claim this is normal vacuum resonance coming from the intake. In my opinion a brand new truck that rattles or jingles upon acceleration has a design defect or there is a defect with my truck. In either case Ford ought to fix it. Fords position is that this is my problem not their problem.
