Oh dear! Thought my car wasn't accelerating properly the other night and now it has been confirmed by the nasty yellow engine management light. It is OK when using the throttle very gently, but any more and it starts to judder and the light flashes for a few seconds. Any ideas please?! It almost feels like a fueling / air flow problem. Have it booked in on Thursday but thought I'd ask and see if you had some suggestions, cheers.
