I don't know man - I'm not well versed in the throttle bodies yet, and looks like yours is an earlier one. I'd say it's possible that you may have damaged something, like the throttle plate, or more than likely threw something out of alignment like the Throttle Position Sensor. If you've got a FSM for your year then start with a throttle body inspection and throttle position sensor check. check the dashpot. Inspect the throttle opener. and adjust if necessary. I'd say look into the trottle body at the valve and if it's fully closed there should be no gaps on top or bottom. YOu might have to adjust the trottle positin sensor.

Just trying to offer some things to consider. .... (from my 93 FSM)
