today I ? arrived in off. a customer with this problem:
the ? happened several times that while it speeds to change gears ( machine already in motion ) just above 2000 rpm, the machine stops and goes in vibration throughout the engine.. but if you accelerate it takes not even gas , and the engine vibrates at all.
approaching a moment, always with the engine running and after a minute ready to leave and the car ? ok.
the lights all turned off.
machine with 90000 km
egr and dpf off, done already, but I said that this was also happened a few times before delete the dpf.
