How can I fix my Audi 80's engine misfires?

My Audi 80 seems to be misfiring when I start it up. The engine shakes and makes a strange noise. It eventually goes away after a few minutes of idling. What could be the cause and how can I fix it?

The most common cause of engine misfires in Audi 80s is a faulty ignition coil or spark plugs. These should be checked and replaced if necessary to improve the performance and smoothness of your engine.

Another possible cause of engine misfires in Audi 80s is a clogged fuel filter. If you haven't replaced it in a while, consider doing so to ensure your engine is getting clean fuel and running smoothly.

It's also important to regularly clean the fuel injectors in your Audi 80 to prevent misfires. A dirty injector can disrupt the fuel spray pattern, causing issues with combustion and resulting in misfires.
