On a 2000 Merc. it's usually an emissions problem. You can try a water dryer for the fuel and change the PCV valve. If the light remains on, then more than likely it's the EGR valve. Have it tested for free at autozone or Advance auto.

If the check engine light is blinking that means that an engine cylinder misfire has been detected

The check " gage " light on in your 1997 Mercury Mountaineer indicates that either your engine oil pressure is LOW , your engine temperature is HIGH or your gas tank is AT OR NEAR EMPTY .
