Engine Management Light Flashing - Car running 'lumpy' (Limp mode?) Hi, I enthusiastically drove 20 miles today when the car suddenly starting juddering when accelerating. 3 mins later the Engine Management Light started flashing. (This one: ) The car appeared to get even lumpier after this with the light flashing when I was driving at low speeds and constantly accelerating and de-accelerating - but when I got upto 50mph with the throttle pedal in a constant position the car drove fine with the light no longer flashing. c**til I put the pedal down even slightly, where it would start juddering again) Would really appreciate any help here and I don't know what to do Thank you, Dan.
