Check the in-line one way valve on the vacuum hose that runs from the cylincer head to the valve on the 'firewall' as you call it. If this is faulty, it will lose the vacuum needed to hold the throttle body open. The last posting is right - the vacuum hoses perish and a leak will kill the TCS system. A quick test on the throttle body is to take the hose off the valve and suc hard - just to see that the throttle body opens. Note that the valve on the bulkhead and inner wheel-arch are NOT the same!
I have the SAAB TCS manual and can provide specific information on most of the components.
Regards.
