possible mechanical issues preventing a good tune?
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.
