Idle too high after TB install...

[Bad89stang]

Just installed a 65mm TB/EGR on my car (because it was basically free) and now my idle is a little too high. It idles at about 900 now instead of 750 where it used to be. It also pauses at 1200 (with the clutch in) after being on the gas and then idles down to 900. I have tried a different TPS sensor and had the same result. I also switched out another IAC, but it didn't work either. Do I need to reset the computer or reset the TPS voltage?

BTW, I realize that I will not gain any performance from the TB until I switch out the intake and heads. I just wanted to put it on for the hell of it. I actually did match the intake with the new TB for what it is worth. I may be crazy, but I think there is a tiny improvement in power. Maybe it is the new shiny parts creating less wind resistance.
