Truck started running rough and stalling. We put a scanner on it and code P1391. So we replaced the crankshaft sensor. Did not change anything. Then we replaced the cam sensor. No change. Replaced timing chain and gears. No change. Checked all grounds and wires.
Any idea of what else it could be?
have the same problem?
