Why is the engine of my Audi 80 shaking?

I've noticed that my Audi 80's engine has been shaking while idling. What could be causing this issue?

First of all, it's important to check for any potential engine misfires or faulty spark plugs. These issues can often cause engine shaking and can be easily resolved by a mechanic.

Another possible reason could be a dirty air filter, which can restrict the flow of air into the engine and cause it to shake. Try cleaning or replacing the air filter and see if that solves the problem.

It's also possible that there are issues with the fuel injectors or fuel pump. If these components are not functioning properly, they can cause the engine to shake. It's best to bring your car to a certified mechanic to diagnose and fix any issues with these parts.
