P304 with issues,
05 Hemi...new coil packs, plugs, wires, crank sensor, intake air sensor, O 2 sensors, clean throttle body, new injectors. I've done a reset on the PCM, I'm getting fuel and fire.
When it's cold it runs good with a #4 cylinder miss but when it warms up it barely gets out of its own way. When it's running ( cold or hot) it has the knock on the inside of the valve cover....doesn't smoke, no water in oil, no oil in water. A visual inspection showed no broken springs, no metallic deposits. I have new valve springs and pushrods to put in....compression check was border line @ 135. Any ideas...knock sensors? Cam sensor? TIA.
