Greetings loyal Saab owners. My 84 900 has 231K, burns no oil and has run perfectly until now. Cold idle runs fine, but once the car warms up, idle is erratic. I have checked many posts to this group and cannot investigate the likely culprit since there is no AIC on an 84 900. In trying to diagnose the problem by looking for vacuum leaks, turns out if I pull off the small vacuum line from the manifold, the car goes from rough idle to a smooth idle. This tells me that I don't have a vacuum leak, but instead, something that is supposed to turn on/off after the car warms up isn't. Any suggestions? Thank you in advance. Jonah
