Engine Performance problem
1995 Ford Ranger 4 cyl Two Wheel Drive Manual 99999 miles
After replacing head after severe overheating, head was cracked in three cylinders, the engines misfires.
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.
Any help will be appreciated.
