Why is my Ford Transit Custom losing power?

I have a 2015 Ford Transit Custom and I've noticed that it's been losing power lately. The engine seems to struggle when I try to accelerate and there's a strange noise coming from the engine. What could be causing this issue?

It's possible that your air filter needs to be replaced. A clogged air filter can restrict airflow to the engine and cause it to lose power.

I had a similar issue with my Ford Transit Custom and it turned out to be a faulty fuel injector. I would recommend getting it checked by a mechanic to see if that's the problem.

Check your spark plugs, they could be worn out and not providing enough spark for the engine. It's a relatively easy and inexpensive fix.
