What can I do if my Audi 80's engine is running rough?

I've been experiencing some noticeable vibrations and hesitations when driving my Audi 80, especially at low speeds. What could be causing this issue and how can I fix it?

It sounds like your engine may be misfiring. This can be caused by several factors, such as a faulty spark plug or ignition coil. It's best to have a mechanic run a diagnostic test to determine the exact cause.

Another possible cause could be a clogged fuel injector. It's recommended to have your fuel system cleaned regularly to prevent this issue.

If you have recently made any modifications to your vehicle, such as installing a new air intake or exhaust system, it's possible that the engine is not getting enough air or fuel. Consider reverting back to the original set up or consulting with a mechanic for proper tuning.
