Why is my Audi 80 model experiencing issues with its engine?

I am facing strange issues with my Audi 80's engine. It is not running smoothly and sometimes even shuts down while driving. What could be the potential causes for this and how can I fix it?

It is possible that the engine's fuel filter is clogged or the fuel pump is malfunctioning. It is also worth checking the spark plugs and ignition coils. If these are not the issues, it could be a problem with the engine's sensors or the fuel injectors.

In my experience, this type of problem can also occur if the engine's air filter is dirty or the oxygen sensor is faulty. It is advisable to have a mechanic check these components and clean or replace them if necessary.
