The engine idle on my Audi 80 seems to be uneven, causing the car to vibrate and make a rattling noise at low speeds. I've tried replacing the spark plugs and cleaning the air filter, but the problem persists. What else can I do to fix this issue?
ReplyMake sure to check your fuel injectors and fuel filter. If they are clogged or dirty, they can cause uneven engine idle. Also, consider getting a professional engine tune-up to ensure everything is running smoothly.
Another possible cause could be a faulty engine sensor. Have a mechanic run a diagnostic test to check for any error codes and replace any malfunctioning sensors.
Check the condition of your drive belt and pulleys. If they are worn out or damaged, it can cause uneven engine idle. Replace them if necessary.
