Ok - as you all know my engine isnt running right. I thought it was the MAP sensor - replaced it and it did no good. Had the codes scanned again and I got PO-0113 - Intake Air Temp high input. Well there is no intake air te4mp sensor on the 5.3. Could having my rear 02s unplugged be causing this? I ordered 02 sims from TByrne and still havnt gotton them in. Its definatly running rich.
