I posted this in the I6 forum but this forum seems to have more activity so i figured I could get more help here. Anyhow, just got done timing the truck and I'm still idling a little high, about 900. Checked the TPS and its reading slightly high at idle; 1.2v. Is it possible someone may have messed with the idle set screw? Resistance at closed is slightly low too, 2.89k, but pretty much spot on at full open, between 340-350.
