Why does my Audi 80's engine misfire when starting?

I have noticed that my Audi 80 sometimes misfires when I try to start the engine. It usually happens when the engine is cold. What could be the possible reasons for this issue?

One possible reason for your Audi 80 misfiring when starting could be a faulty spark plug. Over time, spark plugs can wear out and may need to be replaced to ensure proper engine functioning.

Another reason for engine misfiring could be a clogged fuel filter. If the filter is not replaced regularly, it can become clogged and affect the fuel flow to the engine, leading to misfiring.
