Why does my Audi 80's engine sputter and misfire?

I have a 1995 Audi 80 with a 2.6L V6 engine. It has recently started to sputter and misfire, especially when idling. What could be causing this issue?

There are a few possible reasons for your Audi 80's engine sputtering and misfiring. One likely cause could be a faulty spark plug or ignition coil. Another possibility could be a clogged fuel filter or a failing fuel pump. It's always best to get your car inspected by a mechanic to determine the exact cause and find the best solution.

In my experience, a common issue with older Audi 80's is a bad distributor cap and rotor. These should be replaced every 30,000 miles or so. You could also try cleaning your fuel injectors to see if that helps improve the engine's performance.

I had a similar issue with my Audi 80 and it turned out to be a faulty Mass Air Flow (MAF) sensor. This is responsible for regulating the air to fuel ratio and if it's not working properly, it can cause sputtering and misfiring. I would recommend getting your MAF sensor checked and replaced if needed.
