So my truck is misfiring like crazy and throwing some codes. I saw a thread from someone with p0308 and p0316(same codes different cylinder) but there was never a definite answer and didnt want to bring back a 4 year old thread.

Anyways...2004 f150 Heritage 4.2l...I just replaced my intake gaskets, isolator bolts, fuel pump, plugs, oil/filter, tranny fluid/filter. My plug wires are about 4 months old. Every thing was running fine for about a week then this started kicking in. I pulled my coil pack, checked it and everything was within range according to the Haynes book. I moved the fuel injector from Bank 3 to Bank 1 and moved the wire from bank 2 to bank 3. The plugs have also been checked 3 times to make sure the gap is staying correct at this point.

Anyone have any ideas where to go from here? I'm at a loss.

I have one of the OBDII bluetooth guys in the mail right now so hopefully I will be able to pull any more info you might need very soon too.

Thanks,
Jeremy
