What are the common causes of engine hesitation in the Audi 80?

I have been experiencing a noticeable hesitation when accelerating in my Audi 80. It doesn't happen all the time, but it's becoming more frequent. What could be causing this issue and how can I fix it?

One of the main causes of engine hesitation in the Audi 80 is a dirty or faulty fuel injector. Try cleaning or replacing the injector to see if it improves performance. Also, check your air filter as a dirty or clogged filter can also lead to hesitation.

Another common cause of engine hesitation in the Audi 80 is a malfunctioning throttle position sensor. This sensor helps regulate the amount of fuel and air mixture entering the engine. If it is faulty, it can cause hesitation. Consider having it checked and replaced if necessary.
