If you have an older foreign car, there are never too many options for getting the car fixed. Youtube and forums have helped me quite a bit, and if you also own an older Saab, you know what I mean. That hesitation and cylinder error is likely a $50 part, not something catastrophic. As is the climate control problem. However, there are some issues that require pros with pro tools and experience. If you have a Saab in Jacksonville, that might include a trip to Franz Foreign Car Services.
