Hello together, now I have to open my own thread slowly, after I have already searched for a lot and also asked short questions. The following scenario, 2.5 10V 144 PS automatic bought with almost two years TÜV, 145,000 run, as far as very well maintained condition, but: – The car takes on virtually no gas, acceleration only possible at snail speed, idling O.K. rather low, easy shaking after the warm-up phase, cold start O.K. – What I have done already: I h abe the impression that the car is running too fat, there are now no errors (motor control unit), sitting dog sleeps. I can’t get into the ignition control unit via a flash box, maybe a cause? Where is the ignition control unit? How can I proceed now, can a clogged cat be the cause, although the engine control does not light up? Can the automatic transmission have any influence? As I said, I could still test my other Volvo sometimes But I don’t know how I’m going to make sense anymore. I’m counting on you guys Frank.
