Well so far I am still scratching my head. I checked the seal around my O2 sensors and everything is fine there. I've also spent some time looking for things disconected but everything seems to be in order. The dealership did mention something about when they had the factory air box back on the air/fuel mixture sensor was reading like it was about to go. Can anyone clarify this, maybe point me in the direction where it would be located? (I didn't think such a sensor existed.) I keep going over what Toyota said about ti getting too much air but if TRD has as supercharger for this motor then everyone with that would have a similar problem I would guess.
