In my 1992 9000 2,3l 16V Turbo the red traction control lamp was always on. I was quite happy about this, since the TCS is a pain and there is no way to switch it off in this model. A few days ago the engine suddenly lost performance and I had to jump hard on the acellerator to keep the engine running. This was very unlikely, since this model has got a drive by wire system which normaly doesn offer to much back force. For the next few days I took my other car and left the Saab untouched. Yesterday I started the engine again and it was perfectely ideling. It easely went up with the revs when touching the accellerator which now felt quite normal again. After 3 minutes of idling without moving the car the old troubles came back and the pedal was very hard going again. The engin was very reluctant in taking on speed. When the troubles started I noticed a white flashing TCS light in the odometer.( I never have seen this before, since the entire TCS was not working). It seems that the TCS detects a wheel spin and tries to reduce the engine power by closing the throttle. The only strange thing is, that at this moment the car was standing in front of my home, without any move!!!! Have you got any idea how to solve my problem. Is the TCS part of the ECU or is it a seperate black box?
