Another item to check is the throttle plate. Although you didn't state the year, these engines had Mass Airflow Sensors. If the throttle plate gets coked up, the engine will run poorly at idle, if not stall, but normally runs fine at speed. I clean the throttle plate with carb spray and an old toothbrush. This can cure a lot of rough idle stall complaints. The mass airflow must be clean also to get the proper reading, however it is delecate and should be taken care of by a tech if your not sure about cleaning it yourself. I usually use a q-tip soaked with brake clean because is will not leave a residue. good luck.
