Help 97 Geo Metro throttle position sensor

Hi
We have a 97 Geo Metro with a 4 cylinder.
Recently we began having problems with it staying running until eventually it would not even start at all. A friend suggested we replace the throttle positioning sensor, which made sense, so we did.
Now it starts, no problem, unfortunately, the throttle is stuck WIDE open and will not throttle down. We tried resetting the computer but that did not help. We can’t leave it running long enough to mess with it for fear it will blow up. And don’t really have a clue as to where to start.
Does anyone have any suggestions?
With fuel prices approaching $4 a gallon in Washington state, it would be so nice to have the Geo running again.
Thank you in advance.

There should be a small amount of adjustment on the sensor. Loosen the 2screws that hold it on and "twist" the sensor one way or the other until you get the desired idle. Then tighten your screws back up and that should be it.

sounds like you got the "blades" of the sensor on the wrong side of the throttle tangs, take it off and try installing it again or start it with the tps off but plugged in and see if it will go down to a idle then
