How can I troubleshoot my Audi 80's engine misfire issue?

I have been experiencing a rough idle and hesitation during acceleration with my Audi 80. I suspect it may be an engine misfire. What steps can I take to troubleshoot and fix this issue?

Firstly, check your spark plugs and wires for any signs of wear or damage. If they need to be replaced, do so and see if the issue is resolved. If not, try cleaning your fuel injectors and checking for any vacuum leaks. If these steps do not resolve the issue, it may be a faulty ignition coil or engine sensor.
