Checked compression, low but even. Cam, crank, and oil pump in index.
Retrieved codes of PO 300 Random Misfires, PO 340 Camshaft Position Sensor Circuit, PO 351,352 Ign Coils A & B.
Cam and crank sensors have resistence of.346 K ohms or thereabouts.
Cam circuit has one wire that goes to ground. The crank cirduit does not. I assume that both sensors work the same.
I do not know how to check out PCM.
I never saw the truck run normally before replacing the head.
I don't have ready access to scanner.
Any help directing me in right direction will be appreciated.
