2002 F150 / 4.6. 265,000 miles. Loooking to replace coil packs. Truck has developed a stumble/misfire without any CEL. Also exhaust smells rich like unburnt fuel. Already changed plugs&plug boots/wires. Motorcraft platinum plugs. Stumble still exists at around 40 mph, rpms about 1200, on slight uphill grades. Any feedback on brands to use and brands to steer clear of?

 

2 coil packs or individual coils on plugs? I show the 2002 4.6 has coil on plug. For coil on plug, use Motorcraft, Delphi, or Denso. The same should be good for coil packs.

 

I’ve found that Motorcraft is the only way to go. The rest burn out faster. But that might just be my truck.

 

Denso is the Motorcraft OEM, same coil.

 

Went with the denso COP’s from rock auto. Seemed to have fixed the issue. She’s got her pep back again!!! Thanks for the replies!!
