Does anyone know why my check engine light would come on in a 1999 Explorer? That's really my biggest concern today.


Check your gas cap- replace if it's not sealing properly...
it'll cause a pressure fault. Otherwise have the code read at Autozone or Advance Auto, a place like one of those (they can usually do it for free...) and they can tell you what the problem is.
