Good morning, Since I don’t know any more, I try my luck here. My V70R 2.3 T5 Bj98 jerks if I hold the gas, so constantly want to drive a speed. This occurs only when the engine is warm, in cold condition he drives like a young god. Besides, he has a problem with the stationary gas when he is warm, sometimes even if I don’t save him (left foot brake right accelerator). The car was already in some workshop, the diagnosis was with all the engine control unit since the fifth cylinder fails when the engine gets warm, this was because the injector for the fifth cylinder is incorrectly controlled. When Volvo gave me the same diagnosis, I bought and plugged in a used control unit. The car now drove 100km impeccable. Now it drains again in the stand and jerks at constant speed, but only when it is warm. I am at the end with my Latin. were exchanged: engine control unit spark plugs and cabe l. Crankcase ventilation incl. oil trap injectors
