Why is my Ford Transit Custom losing power while driving?

I have noticed that my Ford Transit Custom is losing power while driving on the highway. Even when I press down on the accelerator, it doesn't seem to go any faster. What could be causing this issue and how can I fix it?

It is possible that your fuel filter is clogged, causing a restriction in fuel flow to the engine. This can lead to loss of power while driving. Have it checked and replaced if necessary.

Another possible cause for the loss of power could be a faulty oxygen sensor. This sensor helps regulate the air and fuel mixture in the engine, and if it is not functioning properly, it can affect the performance of your Transit Custom. Have it checked and replaced if needed.

Make sure to also check your spark plugs and wires. If they are worn out or dirty, they can cause issues with engine performance. Replace them if needed and also consider getting a tune-up.
