Default High Idle Only When Warmed Up

Very strange but after replacing my IAC a couple weeks back, whenever I start my truck after it being warmed up it screams up to 2200 RPM's then after a few seconds it comes back down. If i try to put it into gear it slams into gear as if I have my foot on the gas. Strange thing is, if I start it up cold it starts up real nice and smooth at around 1500. I don't hear any vaccum leaks, I was thinking EGR maybe failing? When Fred was rebuilding my transmission he mentioned it was throwing a code for the TPS, would you guys think this may effect it? Thanks in advance
