Why is my Ford Focus having trouble starting in cold weather?

I recently bought a used Ford Focus and I noticed that it has trouble starting when the weather is cold. It takes a few attempts before it finally starts up. What could be causing this issue and how can I fix it?

This could be due to a weak battery or dirty spark plugs. Have them checked and replaced if needed.

Make sure you let the engine warm up for a few minutes before attempting to start it. Cold weather can affect the engine's performance.
