klint Posted May 12, 2010 Share Posted May 12, 2010 Hello everyone, I would like some advice from you, my Def 110 TD5 2004 with 80000km, has a decrease in performance after a long acceleration, or at highway speed, the engine speed rises but feels little boost, the turbo turns but it is as if the engine was in recovery. If I turn off and on again after 5 minutes or so, the car returns to normal, "ready" and snappy, until I accelerate with all gears at 3000 or much revs or highway or more than 100 km / h. Another thing that i've made, is install a pressure turbo gauge, and the pressure rise at 1,0 or much when the car is normal, while in "recovery" mode rise at max to 0,8 or less. I haven't Nanocom. What could it be?? - MAF sensor replaced new original - MAP sensor / IAT new - Fuel pump was checked and cleaned (but not test pressure) - Fuel filter new - Injector loom new - Throttle pedal new - Wastegate checked and sprayed with WD40 Thanks to all Quote Link to comment Share on other sites More sharing options...
