Yep. I just had a similar experience with my '92 9000T. It was giving TCS faults and going into limp-home mode almost as soon as the accelerator pedal was pressed at all after starting. I read out the flash codes which said there was a TPS fault. I had nearly resigned myself to getting it towed to either the local Saab mechanic or the dealership to get it checked out when I found a vacuum line had somehow blown off from the MAP sensor on the firewall. Luck can be good. Fred W -
