Why does my Audi 80 occasionally have a rough idle?

I've noticed that my Audi 80 sometimes has a rough idle when I start it up. It usually goes away after a few minutes of driving, but it's still concerning. What could be causing this issue?

It's likely that there's an issue with your spark plugs or ignition system. Make sure to have them checked and potentially replaced if needed. Also, consider getting a tune-up for your engine.

Another possible cause could be a dirty or clogged fuel filter. This can affect the fuel flow to your engine and result in a rough idle. Try replacing your fuel filter and see if that improves the issue.
