Hello I’m it again. Volvo 850 106 kw 10v Year of construction 95 and 226 000 km. We have made the valve shaft seal new with the car. He has got original Volvo candles, throttle valve cleaned, air filter new, oil trap cleaned, throttle flap pod new. Tüv and AU passed. But the sprite consumption is now about 14 liters. Before the reperatur it was only 11 liters. And sometimes in idle the speed stays at 1000 sthn. Maybe one of you has an idea. Oh, that’s how the air flow controller was changed.
