I have a '94 960 with idling problem (no idle, very high idle 2000 rpm). The car runs on LGP and petrol and I have the issue in both mode I have changed the idle control valve and the air mass meter (second hand parts) without result For now I have replaced the control valve with a manual one and it is working "fine" in LGP mode, but it is still unusable in petrol mode (the engine speed is fluctuating, and stops, even when I accelerate). It seems that the idle control valve is receiving some bad signals but I don't know which sensors are involved (temperature, AC, pollution, ...). Any help is welcome. Thanks in advance, Stephane
