How to troubleshoot engine hesitation in an Audi 80?

I have been experiencing some hesitation with my Audi 80's engine performance. It's affecting my driving and I'm not sure what's causing it. How can I troubleshoot this issue?

First, check your air filter. A dirty air filter can restrict airflow to the engine, causing hesitation. Also, check your vacuum lines for any cracks or leaks. These small issues can make a big difference in engine performance.

Another potential cause of engine hesitation could be a malfunctioning fuel pump or fuel filter. These parts are essential for delivering the proper amount of fuel to your engine. Consider having them checked and replaced if necessary.
