I recently noticed that my Audi A4's engine has been idling rough. What could be causing this issue and how can I fix it?
ReplyA rough idle can be caused by a variety of issues, such as a dirty air filter, faulty spark plugs, or a clogged fuel filter. My advice would be to start by checking these components and replacing them if necessary.
Another common cause of rough idling in an Audi A4 is a vacuum leak. Check all hoses and connections for any leaks and repair or replace them as needed.
