How to improve the performance of my Nissan Navara engine?

I have been experiencing a drop in the performance of my Nissan Navara engine lately. The acceleration has become sluggish and there is a noticeable decrease in fuel efficiency. What steps can I take to improve the engine's performance?

One possible reason for the drop in engine performance could be dirty fuel injectors. I suggest getting them professionally cleaned or using a fuel injector cleaning solution. This should result in improved acceleration and fuel efficiency.

Another common cause for a decrease in engine performance is a clogged air filter. Make sure to regularly check and replace the air filter, as it plays a crucial role in maintaining proper air flow to the engine.
