Over the last couple of days driving l have noticed the truck sort of very subltey lagging when doing a constant speed 80 or 00 kmh of around on a highway. Also a bit sluggish on acceleration.

The truck hasn't been used much over the last 6 months, starts and idles fine with no fluid on the driveway.

Any thoughts on the possible issues before going to the garage. I was thinking dirty injections.

Many thanks.

Has the fuel filter been changed recently.....?

I cannot recall the last time for the fuel filter, the air filter was changed along with the engine brake and oil 10k km ago.

I'll have them check the fuel filter. Thank you.

Thank you for your suggestion.
