Question type: Maintenance & Repair
Keeps misfiring on #1 intermittently even
after changing both plugs, wire and swapped
coil packs. Would I start looking at a valve
sticking?

Hello. I don't have the cross references. The ECU is programmed to make visible the (wrong) cylinder. You have to cross reference. Unfortunately the info is made unaffordable. Ultimately having to take truck to dealer for repair. Just went through same issue. My advice ... order a set of flamethrower coils and autolite plugs. Careful with #4 cylinder. That's passenger side firewall.

Ok. Thanks for the info. Also, one more thing. With it have 16 plugs, where would I check compression for that cylinder? Top or bottom?
