Hi! I have a 2001 Ford Explorer Sport with a 4.0L V6. Here a short while ago my check engine light came on while driving. My first thought was that it could be the MAF sensor going bad, so I changed it. However, I am still getting a check engine light and I can smell fuel whenever standing near the vehicle and while driving. My father-in-law ran his obd computer and it is reading that it's running too rich on banks one and too as well as a low circuit fault on the MAF sensor. Could the new MAF sensor be at fault or do you think that I have leaking injectors, seeing as there is a near constant smell of gas whenever the truck is sitting still. It's killing me in gas mileage and I'd really like to get to the root of the problem. Thanks for any help or suggestions you can provide!

Get a fuel rail pressure test done, if you have a leaking injector the pressure will drop fairly quickly, check this first.
