Good evening dear screwdrivers and experienced, I shot a V70I cheaply, with fresh TÜV and high mileage. Vehicle data: V70I – 1999 engine capacity: 2.4 power: 140 hp mileage: 330,000km test drive was great, TÜV was made new for me and salesman made a great impression. Now I have the car here and short rides fold without any problems (<3km). After long rides it starts directly and then drains again. If I add some gas, it catches itself and I k ann driving home with a stuttering engine. Under 1,500 rpm he jerks and over it he drives half-way clean. If I leave the alternative for a little longer (30min) he starts again great and then starts to jerk slowly while driving. If I let him stand a day he can start without any problems and drives again his 50km without any problems, if I turn it off then the whole drama starts again from the front. The car is simply great and meets my requirements I would be happy if you stomped me in the right direction or if you told me how best to proceed. From the search function and research I found the following starting points: - possibly defective petrol pumps Relay (already exchanged --> no improvement) – possibly defective spark plugs, ignition cables and ignition distributors – possibly spoiled petrol filter – possibly defective camshaft sensor – possibly defective air mass sensor – possibly After a long trip of 80km with backpackers I could read the following error: P1672 This one has disappeared after 5 short rides. The rucksacks and start difficulties also take place without an error message. So now is my question, how to proceed here best. What do I do first, what is probably, what can I exclude by measuring? Multimeter is available. I thank you already and cordial greetings from guts. city of Poke PS: I screw everything on my motorcycle. That means I don’t have two left hands and can help me well. But car technology is new to me.
