Why does my Ford Transit Custom struggle while driving uphill?

I recently bought a Ford Transit Custom and I've noticed that it struggles while driving uphill. Why is this happening and what can I do to fix it?

This could be because of a lack of power in your engine. It's possible that your engine needs a tune-up or you may need to replace your spark plugs. I recommend taking your van to a trusted mechanic to diagnose the issue.

Make sure you're using the appropriate gear while driving uphill. If you're in too high of a gear, your van may struggle to maintain speed. It's also important to maintain a steady speed and avoid sudden acceleration.

Check the weight distribution in your van. If you have too much weight in the back, it can cause your van to struggle when going uphill. Try redistributing the weight more evenly throughout your van.
