Question about 2003 Saab 9-3
This is usually the first (cheapest) place to start. The MAF (mass air flow) meter is designed to sense and adjust the vehicle engine to changes in air temperature, speed, density etc. to keep your vehicle running properly. Since you already had your EGR replaced (yet another possible source of this sort of problem) I would tend to lean more toward the MAF. If you run any sort of aftermarket intake such as a k&n etc. these can cause problems for certain vehicles that are very sensitive to air flow as Saabs tend to be. Also the oil used on filter elements such as k&n can ruin the sensitive MAF. This unit is generally easy to fix (it's the little box with wires running to it) mid way up your air intake tube just past the filter. They aren't too terribly expensive either. Try this and hopefully this gets you up and running.
