What does the Audi 80 throttle position sensor do and how can it affect engine performance?

I've noticed some strange acceleration and idling behavior in my Audi 80. Upon further investigation, I found out that the throttle position sensor might be the culprit. Could someone explain to me what this sensor does and how it can affect my engine's performance? Thank you in advance.

The Audi 80 throttle position sensor is responsible for monitoring the position of the throttle plate in the throttle body. It sends this information to the engine control unit, which then adjusts the fuel and air mixture accordingly. If the sensor is not functioning properly, your engine may experience issues with acceleration, idling, and overall performance.
