I'm almost tired of saying this, but I can't forsake another 92 9kt owner while he's down.
1. Check and replace all of your vacuum lines. Use silicone lines they will last longer than the car.
2. Check and replace all the one way valves, specifically the one the sits inbetween the intake manifold and the bleeder valve on the false firewall on the passenger of the vehicle.
3. Check and replace all of the grommets that attach the vacuum lines to various places on the intake manifold.
This could clear things up, but even if there was a vacuum leak and it's fixed the system may need to be recalibrated.
Now you need to find a friendly indie with an ISAT. Where do you live, I will try to recommend one for you.
If recalibrating doesn't take, then you want to go ahead and replace the bleeder valve on the flase firewall (about 60 bucks)
Try to recalibrate again. If still no go, I'd do the pedal potentiometer (about $160)
Still no go then try the throttle body ($600)
If still no good then I would try a different TCS brain. The brains are not prone to failure so a used one will do. Just make sure it is from a 92 9000t that has the same kind of tranny as you.
Hopefully that evil light will have gone away before you got to the end of this.
Good Luck,
Chad
