Well, I have looked through the forums and technical documents and have a better idea of what might be wrong with my Saab but I figured that I would post the symptoms and see what you guys might think. The car will start but sometimes you have to hold the gas pedal down and then it seems like it doesn't want to stay running. When it finally starts and goes to idle, it seems like nothing is wrong when it is cold. When it starts to warm up, there is a hesitation and almost like a misfire. That is what lead me to believe that there might be a problem with the head gasket. Also on top of those symptoms, it has developed an overheating problem but I made sure that it never made it close to the red zone on the guage. I have come up with a few different conclusions and have decided that there probably is a vacuum leak somewhere and that the head gasket might be blown. If anyone has any good points on diagnosing the head gasket, please let me know.
