How can I fix the faulty electronic throttle in my Audi 80?

I have noticed that my electronic throttle is not functioning properly in my Audi 80. It is difficult to control the engine speed and sometimes the vehicle does not respond to acceleration. How can I fix this issue?

First, check the wiring and connections of the electronic throttle control module. Sometimes loose or corroded connections can cause issues. Also, inspect the throttle body for any dirt or debris that may be affecting its performance.
