All of the sudden my WJ 4.0 started knocking pretty bad. When I start it, it will idle, sometimes rough sometimes ok, all still with the knocking.
If I give it any gas, it starts to miss, and wants to die.
I was getting a P0340 code, so i changed the Cam Position Sensor, not the synchronizer, just the sensor.
No more P0340, but still doing the same as above, only now getting P0351 and P0352 codes.
I have a youtube vid of the noise @
