Diagnosing and Fixing Faulty Spark Plugs in Audi 80

My Audi 80 seems to be having trouble starting and running smoothly. I suspect it may be due to faulty spark plugs. How can I diagnose and fix this issue?

First, use a spark plug tester to check if the plugs are working properly. If not, replace them with new ones. Additionally, make sure to check the spark plug wires and replace them if necessary. If the problem still persists, it may be a sign of a bigger issue and it is best to take your Audi to a professional mechanic for further diagnosis.

To properly test the spark plugs, remove one at a time and check for any signs of wear or damage. If the electrodes appear corroded or worn, it is time to replace them. It is also a good idea to clean or replace the air filter while you have the spark plugs out. Remember to always use the recommended spark plug replacement for your specific Audi 80 model.
