Often heard limp mode mentioned over the years but never experienced it - until now. (possibly) So twice now the car has lost power, EML comes on and then it sounds like it's running on 3 or possibly even 2 cylinders, a bit tractor like. Very little power, needed to change down to maintain any reasonable speed and keep the revs up to make progress. After switching the engine off and starting it again it all clears. No EML and no codes to indicate anything was wrong.
So is this known as limp mode?
