You need to see what the code is. Most likely it is an O2 code or EVAP code both are very popular on that model.


there is a crack (or cracks) on your gas filler neck (usually near the gas cap) and the computer is detecting that gas fumes are leaking. That's what the code was on my 2001 Explorer Sport.
