Hoping that someone can help me diagnose a problem.



My car will be running fine down the highway and then the tcs light will come on, the car will lose power...cannot drive.....have to pull over..turn off...restart immediatly...idle at 100 rpm struggling..try to drive wants to stall.. if i leave it alone for 20 minutes it will restart and drive like nothing happened for a bit before repeating the problem. This happenes at idle and while driving.



This first happened on the highway between whistler and vancouver....not the kind of highway you want to pull over and wait for tcs....any advice much appreciated.

I had similar conditions, I replaced the valve on the fire wall by passenger side. Also there is the same valve P/N, by the battery mounted on the fender well, I think it is for the cruise control, one can switch the valves and try if this elimantes the problem. This is the most common problem. Also, I found a loose coupler pin connection going to the TCS computer located under the drivers seat. The cars trouble diagnostic system lead us to the trouble. We tighten it and so far it is working. The Saab techs want to replace the coupler with a gold wash type of connection. Anyway good luck. oscarjohn
