4.7 knocking above 2k RPM
I have an 03 Ram 1500 4x4 with a 110k miles. It has started pinging or knocking above 2000 rpm. It will workout or go away after a little driving, but if I stop it will start all over again. I know the PCM will begin to retard timing only above 2000 rpm based on signal from the knock sensors. I have done check per service manual and sensors check ok. Anybody have a solution. Most post I have found online say even the dealer can't figure it out.
