I’m proud to be the owner of a 96er 850 GLT – 2.5 20V with automatic transmission. I’m very satisfied with my Volvo so far. A living room on four wheels. Simply very relaxed travel/cruisen. However, for some time now he worries. He has idle running problems. The speed suddenly slows down. Sometimes he goes out. I have an odyssey through workshops behind me. So far have been changed: Lambda probe, LMM, throttle flap pot, throttle flap was cleaned, oil trap/flam sieve were made, ignition cables, spark plugs, ignition distributor cap and runners are new …. … Error is still there. Now I have observed this again very closely. Here my problem description: If I go off at first show no problems. Only after about 15 minutes of driving it goes off worse. First thanks only the speed drops short, then it always gets worse and the engine dies even if I don’t give up fast enough gas again. However, if I don’t do it all the worse then the brake bit.
