Hi, I own a 2006 euro 3 isuzu nkr turbo intercooler 3.0 truck. When cruising over 50mph and over 2000rpm the "engine check" light comes on and I lose power. Once the engine drops below 2000rpm and whilst under 50mph the light goes out and I again regain power. Note: the engine does not cut out, the engine does not respond to the accelerator. If I press clutch pedal and accelerate the engine revs up may go up to 4 thousand rpm. The fault analyzer showed code P0216 code and so far I have changed fuel filter. Ample fuel is delivered at injector pump and the tiny filter on the inlet located at injector pump is clean, I have further placed clips on all fuel hose lines. I have also noticed that when I drive erratic I can get the vehicle to a very high speed however when I cruise at that speed or keep that speed the "check engine" light comes on again and I lose power. Please help.
