Bryce,
I had a similar problem with my 96 900s. I have learned that 2 items will not register as failing on the Tech II computer. They are the bleeder valve and the purge valve. I you have a bad vacuum hose the above two valves can fail. This results in effect to the engine getting flooded with fuel which blackens the plugs and injectors get fouled. A long trip helps clean them but city driving returned my problem just as you have.
I had the valves replaced for about $250.00 with labor and the problem stopped.
About 9 months later the symptoms returned but the car also stalled when driving and would turn over but not start on startup sometimes.
You could have a bad ignition relay switch. If your car stalls when running, or your dash panel lights are dim sometimes or the engine turns but does not fire on startup this would indicate need for replacement.
This cost another $ 270.00 with labor.
Good Luck.
John
