'93 4.0L-- idles at 1700 rpm!

Recently I replaced the O2 sensor on it, and cleaned a sensor in the throttle body (held in by two torx screws, had a black rod with a silver tip on it, not sure what it was, but it was nasty). Since I did that, it's been idling at 1700 rpm! Needless to say, this is damn hard on the tranny when putting it into gear.

Any ideas as to what could be causing this? It was running way rich with the old O2 sensor and was idling about 1500.

Thanks
CHris

I postec on a different subject about idle, but disconnect the battery for 1 hour, then reconnect and drive the car a few miles. Should come back to normal.

Sounds like the IAC (the part you cleaned) is stuck and/or dead.
