How to fix engine ignition issues in an Audi 80?

I'm having issues with my Audi 80's engine ignition where it struggles to start and sometimes misfires. What could be causing this and how can I fix it?

One common cause for engine ignition issues in an Audi 80 is a faulty spark plug. Check and replace any faulty spark plugs and see if the issue improves. If not, consider checking the ignition coil or control module as well.

Make sure you are using the correct type of fuel for your Audi 80. Using the wrong type of fuel can cause ignition problems and affect your engine's performance.

If the issue persists, it could be a problem with the fuel injectors or fuel filter. Have a mechanic check and clean or replace these components as needed.
