I have noticed that the idle rpm of my Audi 80 is constantly fluctuating between 800 to 1000 rpm even though the engine is warm and under no load. What could be causing this issue?
ReplyThis could be due to a dirty or faulty idle air control valve. It is responsible for regulating the idle speed of the engine and can get clogged with debris over time. Try cleaning it first and if the issue persists, it may need to be replaced.
Another potential cause could be a vacuum leak. Check all the hoses and connections in the vacuum system for any cracks or leaks. A vacuum leak can disrupt the air-fuel ratio and cause fluctuations in idle rpm.
Have you recently changed your fuel filter? A clogged or dirty fuel filter can cause inconsistent fuel flow to the engine, resulting in erratic idle rpm. Consider replacing the fuel filter if it has not been changed in a while.
