How do I troubleshoot a faulty ignition coil on my Audi 80?

I've been experiencing intermittent engine misfires and suspect that my ignition coil may be failing. How can I diagnose and fix this problem?

First, you'll need to check the resistance of your ignition coil using a multimeter. If the resistance is outside of the manufacturer's specifications, then you'll need to replace the coil.

If your coil's resistance is within spec, then you may want to check the spark plug wires and connectors for any damage or corrosion. These can also cause engine misfires.

Another possibility is that your ignition control module is failing. If you suspect this, you'll need to take your car to a mechanic for further diagnosis and potentially replacing the module.
