I have a 1998 dodge ram 318 has been losing power. I have 120-150 pounds of compression in every cylinder. Replaced cap, rotor, wires, both 02 sensors, map sensor, tps, idle control, coil, intake gaskets, fuel pump, crank position sensor because it was and still is throwning a 1391 code. My rear 2 cylinders on both sides are fouled out. I do get a bank one or two (not sure)fault in the fuel system. I still get the 1391 code and have not changed the camshaft position sensor. I have 160, 000 on this motor, did the heads about 40,000 ago. Any idea what is causing the rear 2 on each side to foul out? Going to get cam sensor but what else is there. Has NO power. Also backfires and pings
have the same problem?
