May have a fuel leak that would need to be found ASAP, or it could be coming from the EVAP system, which also needs to be checked out. If the check engine light is on, probably coming from the EVAP system.

It's going to be your fuel regulator, top of engine on drivers side under neath the plastic cover. Pretty darn common on our platform with the I6 engine.
