Pump 92 No Fog'r V2 - 5th gear DTC WOT pull (Mixture control 2, Misfire Cylinder 6 CEL)
Gapped the 2 step colder plugs down from stock to .022 and seem to have solved the ignition problem I believe. Now seem to be getting throttle closure and maxed fuel trims. Perhaps the cause of the remaining cylinder 6 misfire.
