9-5 2001 2.3 turbo saloon. Engine warning light came on. After diagnostic check garage said just a phantom light and it had switched off. Came on again few days later but engine ran normally for approx three weeks.Today engine cuts out as soon as throttle lifted but runs ok if some revs. As automatic difficult to drive.Anyone any ideas of possible fault. Always used fully synthetic and regular oil changes. Any ideas/suggestions appreciated.
