I getting knock retard at part and full throttle, driving the timing down to nearly nothing, and even off throttle is showing knock retard. The engine isnt tired or noisy at all so I dont suspect an internal mechanical noise to be at fault.
anyone else have an opinion on this amount of knock retard showing up? Im thinking maybe the sensor is failing. But unsure if anyone else has run into the same situation.
09 4.3, using TR6 plugs,93 octane, stock timing / fuel maps.
