Engine Slight Knock @ 3000 rpm's?? :help:
It seems to be running EXTREMELY RICH n around 3 Grand' it knocks. But with the throttle down anywhere above or below that it goes away... And it seems to only do it in Idle... I've done a recent Tune Up +... Cap, Rotor, Plugs, Wires, Knock Sensor, Thermo., MAP sensor, replaced ALL GASKETS... PLENUM DOWN even an alternator and starter... I was told possibly to replace the PROM n The ECU... Any input would be greatly appreciated
