Oil pressure
Get yourself a NAPA Gold filter 1060 (iirc part number), and some 10w30. I've heard of guys picking up 5lbs just by switching to this filter. Hopefully you haven't done damage to your motor.
And get it out of your head that the "Check Gauges' light is causing your car to stall. It is coming on as a result of you having low oil pressure at low RPMs when the car is about to stall.
