possible mechanical issues preventing a good tune? I had a tune done locally on Monday for my new cam and torque converter, but I'm having some issues with it now, especially relating to idle. The driveability is definitely way better all around, but when it tries to idle, the idle is too high, it idles to 1600-1900rpm when moving, dies when it goes into gear, takes a while to settle into idle at a stop out of gear, and sometimes it will go to 1900rpm idle if I hit the gas on a cold startup. Warm startup is worse than all that most times 
The thought was since there was some oil in the intake and throttle body, it could have fouled up the IAC motor as well...plus the PCV calce probably needed to be replaced. I replaced the valve, and am getting ready to go clena the IAC motor, but is there anything else that this sounds like it could be? The tuner worked pretty much all day on it and the car was just being a bear all around...I want to get everything that would be mechanically possible fixed before I take it back to him.
