Why does my Ford Transit Custom feel sluggish when accelerating?

I recently purchased a Ford Transit Custom and have noticed that it feels sluggish when accelerating, especially when going up hills. Is this a common issue with this model? What steps can I take to improve the performance?

One potential cause for sluggish acceleration in a Ford Transit Custom could be a dirty air filter. Try replacing the air filter and see if that improves the performance.

Another factor that could affect acceleration is the fuel quality. Make sure you are using high quality fuel and consider using a fuel additive to improve engine performance.
