Engine Performance problem
2003 Other Nissan Models 4 cyl Four Wheel Drive Manual 92000 miles
Navara D22 2.5Di Loss of power in 3th & 4th gear just like the turbo is not working but all ok in 1st & 2nd and fill ok in 5th gear. Also some times you can fill a hesitation when in 3th as if it wants to go but holds back (just flat).
To add I have been told that there are to sensors one on the fuel pump and one on the air cooler. We have changed the fuel filter and checked the fuel lines etc. But no change.
Hope you can help !
