How do I fix my Audi 80's engine misfire?

I recently noticed that my Audi 80 is misfiring and I'm not sure what could be causing it. The car seems to be struggling during acceleration and the check engine light is on. What could be the issue?

You may have a faulty ignition coil or spark plug. These are common culprits for engine misfires and can easily be replaced by a mechanic. I would also recommend getting your fuel injectors cleaned.

Have you checked your engine's air filter? A clogged filter can lead to a poor air-fuel mixture, causing misfires. Consider replacing it to see if it improves your engine's performance.

It's possible that your Audi 80's timing belt needs to be replaced. If the belt is worn or damaged, it can cause the engine to misfire. I would suggest taking your car to a mechanic for a thorough inspection.
