Question about Ford F-250

1 Answer

My 1992 ford f-250 used to get 17 miles to the gallon, now it idles high and I get horrible gas mileage. I ran the codes but it tells me the system is fine. I have metered TPI sensor and it reads good. I also put a brand new O2 sensor in it, that did not help. I dont know where to look now since the trucks diagnostic reading came back good 111 on both KOEO and KOER. Every once in a while the truck drops to correct idle but raises back up within seconds. Can anybody point me in the right direction? Thank you for your time.

You need to provide your driver habits, any check engine light issues. Exactly how many miles to the gallon are you getting in town, freeway and combined?

Gas tank size , gas gage does not work , how many miles to the gallon the grand caravan get?


The gas tank capacity is 20 US gallons, but the tank will really only hold about 19.5 gallons. As far as mileage goes that really depends on your driving habits and the load it carries, just you? more? I would think that your average miles to the gallon would be in the range of 14-16 town and highway.
Here is the EPA ratings, which never match the real world gas mileage.

Why is my 2002 Chevy Cavalier horrible on gas? I am only getting 17 miles to the gallon. I have a CNG tank but no filling station close by. Could the weight of the tank be affecting my gas mileage?


Cars are just like airplanes. Weight will always have an effect on fuel milage. Check your tire inflation. We find, in our shop , that low tire inflation in the biggest cause of poor milage. (beside a lead foot like mine)

Getting a P0505 code:Air control system. Replaced IAC and still get the same code. Idle is rough and gas mileage is down to 4 miles to the gallon.


You really need to look in the computer at the data. Anything that can allow excess air to pass over the 02 sensor will cause the PCM to add fuel to achive a 14.7 to 1 air fuel ratio. The data will tell you if you have an idle issue or a cruising issue since both scenerios use differnt sensor inputs. Its possible you have clogged fuel injectors or maybe you just got a bad batch of fuel, or both

I have a 92 Saturn SL-1 and it runs fairly smoothly except the auto. transmission shifts hard at times. However, the gas mileage has dropped to probably 15 mi per gallon. I have replaced the fuel filter,...


Try changing fluid and filter. If this does not correct it, then test the vacuum pressure in the vacuum controlled actuator and the circuit on the tranny. If it turns out ok, then tranny servo or other internal part may be faulty

I am getting horrible gas mileage... engine dieing


Look for a hole or leak in your air intake tube first, then do a basic tune up...plugs/rotor/air filter/dizzy cap (if needed) and inspect vacuum lines for cracks......these would be the most common causes of your problem

I have a 1997 ford f-250 4x4 and its lousy on gas


You could fill the tires with Nitrogen but it will cost about $15 a tire. You will gain 1.5 - 2 miles more a gallon. Big trucks were made for pulling and hualing only. If your looking at gas mileage then you need a focus.

Gas consumption


My Answer:

Poor gas mileage can be a result of many many things.

First of all you need to find out what is the factory normal gas mileage for your model year Jeep SUV. It should have said on your window sticker if you bought it brand new. If you are a 2nd or 3rd owner then a Jeep dealer would have info. Google search will tell you as well, and only takes a couple minutes to find.

I did a quick Google search and for a 2003 Jeep Grand Cherokee with a (4.7L V8 engine) the average mileage is roughly 14 mpg.

Not sure what engine you have as to options, etc?

How you drive will greatly change that number up or down depending on a number of driving and driver variables.

A few being -

Driving habits?

Tire pressures?

Engine tuned up?

Lube & oil/filter changes (every 5,000-7,500 miles? Air filter changes (every 10,000-15,000 miles)? Read your auto manual for exact recommended intervals.

How many people in the SUV on average?

Are you towing anything?

Type gas you are burning - BRAND? (See injectors below)

Area you are driving in (hills and valleys verses flat out,
etc)

Jeeps in general don't have a good track record for great mileage, and rough engine idling is always a clue that your fuel injectors are dirty. Typical on all Jeeps with port fuel injection systems! On Jeeps with dirty fuel injectors your mileage will go way down accordingly. If your not putting at least a 12 oz bottle of say Walmart brand Super Tech Fuel Injector Cleaner (~ $1 each) in your gas tank religiously every logged 1000 miles, or every 2 tank fill ups, then you are just inviting dirty fuel injectors and POOR fuel economy!

My 1993 Ford XPLR with a 4L V-6 engine (and ~ 160,000 flawless driven miles) gets roughly 22 miles per gallon on the highway with cruise control on, and about 17 around town on average. I religiously put a 12 oz bottle of the above injector cleaner in my gas tank every 1000 miles!! Of course I do all my own tune-ups, general repairs, and suspension maintenance (shocks, O2 sensors, trans oil changes, lube & oil/filter changes, code reading and clearing, etc) myself and it shows! I don't trust repair shops except for say Tires and Balancing at SEARS.

Hope that helps ease your mind about gas mileage as it relates to your Jeep there.
