What is the most common cause of engine misfire in an Audi 80?

I recently bought an Audi 80 and have been experiencing occasional engine misfires. I'm not sure what could be causing it, but I want to address the issue before it gets worse. Can anyone provide insight on the most common cause of engine misfire in an Audi 80?

The most common cause of engine misfires in an Audi 80 is a faulty ignition coil or spark plugs. These components can wear out over time and cause misfires, so it's important to have them checked and replaced if necessary.

Another common cause of engine misfires in an Audi 80 is a clogged fuel filter. This can restrict the flow of fuel to the engine, leading to misfires. It's recommended to have the fuel filter replaced every 30,000 miles.

If you have an older Audi 80, it's possible that the timing belt has worn out. A worn timing belt can cause the engine to misfire due to misaligned engine timing. Make sure to have your timing belt replaced every 60,000 miles.
