I have a 2000 C280 Sport which recently started to have a rough cold idle and the car leaps/ jerks when trying to drive reight after starting. The problem goes away if the car is warmed up before driving. The ABS and Check Engine lights also have come on - the ABS light goes out but the check engine light stays on. Any ideas about what's going on? I've seen a post with a simialr problem on a 1997 C280 but thought that the cause is not the same since my car is a later model.
