So I’ve had a problem with my truck recently and posted about it but here’s the codes I have thrown.

Cylinder 1 misfire
cylinder 2 misfire
bank 1 too lean
ignition coil a,b,c malfunction
misfire on startup and random misfire
this is all going on but the starting problem was with cylinder 2 which I changed COP and plug with no solution.

changed coil packs on all the issue cylinders, along with the plug and injector on cylinder 2.
yesterday I test drive the truck it seemed to to run almost normal for a few seconds at idle and then as I went uphill I was throttling on it and would only get about 15-20mph out of her with terrible clanking noise. I didn’t want to keep driving but also was not in a position where coming to a stop for a tow was possible.
The coil pack codes have gone away but I still have misfire codes along woth both bank 1 and 2 being too lean, guys I’ll take any help I can get at this point. I’m starting to hate this poor truck.

 

It might help if you identified what you're working on....

Also, post the explicit fault codes, not interpretations.

Between cylinder 1 & 2 misfires and the clanking noise it sounds like you're getting coolant into the cylinder, meaning a possible blown head gasket. When it runs do you get white steam out of the exhaust?

If you have a 97 or 98 with a 4.6 motor using coil packs instead of COPs, then you could be looking at one or both coil packs going bad, or a wire to them.
