For 97 with ME 2.1 , you should get a check engine light if there is a problem. This system is complete throttle by wire so any error will trip a code / light. 96 was the half electric throttle / half physical connection.

The throttle peddle potentiometer is near the brake master cylinder. Have a look at the cable and follow it back to the pedal. With the engine off push the pedal and observe the reaction under the hood.
