I'm new to all this, so i have a 2018 l83 n a 6l80e that I swapped into a 97z71 with a stand alone harness n programmed by swaptime. I get several different things happening. If I tap the throttle it delays a few seconds then revs up pretty high around 5k without my foot on it. With the scanner running the mph will sometimes be 255 n the rpm might not be reading, and the next time right the opposite. It might not be showing the map reading, it kinda jumps around to different things. Has anyone else experienced anything like this? When i read the engine OTC's P0097I intake temp sensor 2 circuit low.. P004 humidity sensor circuit low...PO113 intake air temperature sensor 1 circuit high.. PO691 fan 1 control circuit low. Any help would be greatly appreciated.
