Hi Gerald! My car is a 1987 Saab 900i and the problem with the warm up sounds familiar to me. I think, you are in the right direction with replacing the warm up regulator and the auxiliary air valve. What you schould do next is measure the control-pressure on the cold and warm engine or even better watch how the control pressure changes while the engine is warming up. All you need to do this is a manometer (0-6 bar) and some connecting equipment. A manometer for measuring airpressure works fine. You can know adjust the control-pressure. (The adjustment is done with a screw and tiny spacerdiscs on the "Kraftstoff Mengenteiler", I dont know the english word for this. If you need the exakt adjustment procedure or just the values of the control-pressure, send me a mail. But there schould be something about that in your manual about the Bosch K-Jetronic injektion system? If the control-pressure is to low, the engine runs to rich. There is a temparature switch in the coolant cycle and a switch for the a/c. Both are in connction with the fuel and air system. But I do not remember exactly, what these switches do. I will have a look in my documentation for the K-Jetronic. Let me know, if your problem persists.
