How to diagnose and fix a misfiring engine on the Audi 80?

I have an Audi 80 that has been experiencing engine misfires. I have checked the spark plugs and ignition coils, but the problem still persists. What could be causing this issue?

The most common cause of engine misfires in an Audi 80 is a faulty ignition control module. Have a professional mechanic take a look at this component and replace if necessary. Also, check for any vacuum leaks as they can also cause misfires.

Another possible cause of engine misfires in the Audi 80 is a clogged fuel filter. This can restrict the flow of fuel to the engine, causing misfires and other issues. Consider replacing the fuel filter if it hasn't been changed recently.

A malfunctioning mass airflow sensor can also lead to engine misfires in the Audi 80. This sensor measures the amount of air entering the engine and adjusts the fuel mixture accordingly. A faulty sensor can cause an imbalance and cause misfires.
