How do I troubleshoot a loss of power in my Audi 80?

I've noticed a decrease in power while driving my Audi 80. What could be causing this and how can I fix it?

It's possible that your air filter is clogged and needs to be replaced. This can affect the performance of your engine and lead to a loss of power. I recommend checking your air filter and replacing it if needed.

Another potential issue could be a faulty ignition coil. This can cause your engine to run rough and experience a loss of power. If your ignition coil is indeed the problem, I suggest replacing it as soon as possible.

Have you checked your fuel filter? If it's clogged, it can restrict the flow of fuel to your engine and cause a decrease in power. You may need to replace the fuel filter to resolve this issue.
