you either had a line pop off during reinstallation (or a mistake in tube routing), or your throttle body blade redo got messed up a little. Just seems like too much air. maybe you should double check the throttle angle and not the electrics.

Mike,
Yes I know about setting the TPS v, but that is affected by the Min Air adjustment. You need to get the throttle blade opening correct before you can set the idle TPS voltage properly. It's an iterative process.
Turn the key ON, then pull the IAC CONNECTOR. This should block the IAC port to the throttle body. Then start the motor. Does it idle, and if so at what RPM?
If it's too high, you need to close the throttle blades till you reach the desired idle speed. You actually set it a bit lower so you get some IAC control over the idle. Whenever you adjust the throttle blade, need to re-check TPS voltage and adjust if necessary so it is below the idle voltage threshold. Otherwise, ECM won't use the correct Spark Timing and you end up w an idle hunt.
