Weak throttle 2003 Mercedes Benz c320

Asked by: 36 views Engine Question

2003 Mercedes Benz c320 wagon. When I press the accelerator hard enough a check engine light comes on and the throttle is very weak after that, I would have to hit the pedal to the floor for my RPMS to hit 2 thousand. If I shut the car off and then on the check engine stays there but the throttle is fine until I accelerate from there.

    Hello

    The engine is doing that because it goes into Limp home mode and it resets when you restart the car and then working fine. Often limp home mode reduce the power alot and put rpm limit on 2-3000 rpm.

    Could be alot of things that is causing limp mode.
    What you have to do now is to read the dtc fault code memory. Because when it goes into limp mode there is some fault stored in the memory and it’s not worth to guess whats the problem.

    When you find out what trouble code is stored, then I can help you out what to do next! 🙂
