Throttle Position Sensor Fouling

After doing much reading, it seems that my idling problems (http://www.toyota-4runner.org/showthread.php?s=&threadid=14920) are symptomatic of a TPS out of adjustment.

The idling problems occured immediately after cleaning the throttle body. I opened up the plenum, completely hosed down the inside with throttle body cleaner, and brushed the bejesus out of the innards with a copper brush. Could this have caused damgage to the throttle body, or at least cause my idling problems?
