2002 Chev Trailblazer

When idling, check gages light comes on and oil pressure gage drops. Returns to normal when accelerating. Not level issue; monitor oil level regularly

  1. Most likely just need to replace the oil pressure sending unit. Quite common. You can always remove the sending unit and confirm the pressure with a separate gauge. I recommend just replacing the sending unit and that should take care of it.
