What are the common issues with the Ford Transit Custom's engine?

I recently purchased a Ford Transit Custom and have noticed some unusual behavior with the engine, such as strange noises and stalling. What are some common issues with this model and what can I do to prevent them?

It's possible that your engine is experiencing problems due to a faulty spark plug or fuel filter. I would recommend getting these checked and replaced if necessary.

One common issue with the Ford Transit Custom's engine is a clogged air filter, which can cause it to struggle during acceleration. Regularly changing the air filter can help prevent this.

If you have noticed a drop in fuel efficiency, it could be due to a dirty fuel injection system. I suggest getting a professional cleaning or using a fuel system cleaner to improve performance.
