Could an issue with the Audi 80's fuel pump be causing high idle speed?

Recently my Audi 80 has been idling at a higher speed than usual. I've checked the spark plugs and air filter, both seem fine. Could there be an issue with the fuel pump that's causing this? What should I do to fix it?

Yes, a faulty fuel pump can definitely cause high idle speed in your Audi 80. It could be due to a clogged fuel filter or a malfunctioning pressure regulator. I suggest getting it checked by a mechanic and replacing the pump if necessary.

Make sure to also check for any vacuum leaks, as those can also contribute to high idle speed. A smoke test can help locate any potential leaks. If none are found, then it's likely an issue with the fuel pump.

I had a similar issue with my Audi 80 and it turned out the throttle body needed to be cleaned. So before replacing the fuel pump, try cleaning the throttle body and see if that helps.
