Hello, all of a sudden, the engine becomes totally lame, when I give the foot of gas is always a hectic “automatic” gas giving so from 1,500 to 2,500 U, then it falls down again and goes up again on its own, then the idling falls off again, then up again. In the stand funny stuttering. If I want to start at the traffic light, totally lame and can drive just so about 40 km/h, no gas acceptance at all. It is the warning “motor maintenance urgent”. I sometimes have the message ” Engine maintenance required”. What can that be … I should probably only drive to the next workshop… V70 II, 2.4 L, 170 hp, year 2001, 165,000 km
