    Is any one have experienced a vibration when using stage 3 engine brake. I also noticed that when the ECO-ROLL is on when and the truck shifts to neutral costing,I also feel it vibrating. I have 2014 d13 with I shift combo.

    I have same vibration on engine brake stage 3. My mechanic sad that my injectors are going bad. I know it does not sound logic but on stage 3 engine brake, fuell injects in combustion chamber for better braking power

    That makes no sense you need a new mechanic .. Fuel creates acceleration not deceleration ..

    It does. Injected fuel creates more power energy inside combustion chamber while using engine brake. Do more research on D13 engine.

    It’s the variable geometry turbo that creates more energy braking on stage 3

    To me it feels more like drive train vibration than engine. I also feel very similar vibration when the truck is rolling in ECO- ROLL.

    No no no. The injector pulse is Zero on deceleration.... Zero.

    If fuel is getting in the cylinder, the injector is leaking , etc
