The guys here who r using 2010 v6 that I've spoken to are getting around 13 to 15 mpg. I use 93 octane gas. Injector cleaner once in every 20 full tank fillups..

I keep thinking gas leak somewhere but never smelt it. Not even once.

Does it run rough at all? You could check your fuel filter.

The 4.0 should be able to pull 20s easily. My 4.6 2v averages 13-14 around town which is actually bad mpg for it. And I get around 18-20 highway, which is also considered bad mpg. On a 91 octane tune.

Seems like everything should be fine. Maybe it's your foot.

Actually I've been thinking about it.. And wondering if it's worth the price including shipping. If I buy one online from sct or bama, how would they set it for my car? There are no dealers here. Atleast not authorized dealers that I saw. We'll not for bama. Sct has but is asking about 3 times the online price for a tuner.

Thanks, makes sense.

Hi guys.. Can you post a few pics of your engine bay? So that I could see if I can notice anything wrong with mine or anything out of place? Or maybe mail me to me? Thanks...

What's your hwy mileage? I have no idea about 2010's EPA info (look for it) and if yours is consistent with it (by -2mpg at the most), you might have to change your local driving habbits.

Just find a good straight road and see how much gas your pony is chugging out. If its crappy and as you haven't found any issue thus far, my suggestion would be to go buy a 3.7 lol

Well seems like you don't have any mechanical problem. I have a 2014 v6 and my city mileage is pretty crappy (13ish mpg) -in stop and go traffic at every other traffic light, and I have a manual. So if I have read all of your posts correctly, its no surprise you havent found any physical evidence that shows xyz thing is the reason.
Just enjoy your ride man, this gas mileage stress isn't going to help your cause.

Hi guys.. N gals..
Further to my issue, mpg, I have a noobish question. Well Coz I am. Lol.
As I've said my mpg has been **** so far m I've tried everything to fix it or diagnose it, other than take it to a mechanic. Coz I ain't got the cash for it right now. Was messing around the car as I always do, 2 days ago n I removed the connection off a sensor which I'm assuming is the fuel rail pressure sensor? Prior to this, my obd scanner has always said I'm running lean by about 12%. Always. After this, it now says I'm running rich. Between 7% to 9%. Is this a false reading Coz the pressure sensor is disconnected? Also, mpg, as per the dash has been holding at between 19 and 20 city driving. Can't be sure till the next fill up I guess. Attaching some pics.. And advice guys?

I'd plug that sensor back in. Ford (and most others now) use a single fuel line from the fuel pump (in gas tank) to the fuel rail. This is to prevent vapor lock (fuel getting hot and bubbling in the fuel line). If that is the fuel rail pressure sensor, then you will have problems with it unplugged. It sends a signal to the engine management box, which in turn informs a module (located under the rear seat) to turn on/turn off the fuel pump. This is how the fuel pressure is maintained in the fuel rail to the fuel injectors.

I'd save some money and then get your problem diagnosed properly. By unpluging sensors and running the engine for long periods of time, you may cause more codes to get set, and/or additinal problems. We all as internet shade tree mechanics have to determine our lack of proper resources and get qualified help when the time comes.

I second this. Your lean/rich reading is likely false because your engine temp didn't go up - engines that run lean run hotter. (Something I learned in flight school)
