I have a '01 Ranger V6 3.0 Edge and i am getting awful gas mileage(10 city, 14 hwy), I have tried everything, new plugs and wires(gapped properly), cleaned the throttle body, cleaned the MAF, new fuel filter, new air filter, new PCV valve, and i have also tried injector cleaner, and made sure the tires are properly inflated. NOTHING seems to work! Can anyone post any ideas that you have? im going to try everything i can, thank you so much!!

 

There was just another post about a guy that had a split in his intake gasket, causing a few problems, one of them was gas mileage.

 

No check engine light codes? No overheating? Sounds like you have something maybe a little more serious, especially if you already tried the cheap easy fixes.

There are performance upgrades you can do to help. Underdrive pulleys, e-fan. Also, lay off the skinny pedal, lol.

 

the fact that its a 3.0 isnt helping much lol

 

i have a v6 4.0 and my MPG's are going down very fast. not sure what it is but i know a tune up is needed! Plugs, wires, fuel filter, change all the liquids. that sort of stuff

 

No codes, no overheating, and im not a fast driver, im not slamming on the gas or anything like that, im not sure what else to do though, lol im running out of options!

 

there are a few mechanical things you can check too. try checking the drag on your drum breaks. i recently did an explorer axle upgrade with disks and got better mpgs out of less drag via less contact patch on the pads. also just because there are no CEL lights doesnt mean somthing is not coming. it takes some many times of the issue to occur before it trips the light. look into having a live diagnostic done and see just what exactly is going on

 

I have gotten a diagnostic test done before and nothing came up, and would there be more drag on the drums or disks do you think? Because i just changed the front brake calipers to make sure there was not any drag, how big of a difference in mpg do u think it helped?

 

well i know when i had my car i had a drum dragging and after i had it fixed i saw a 2-3 MPG increase

 

What a out a cold air intake?

 

theory behind cold air intake (CAI) is that cooler air is more dense with combustible molecule like oxygen and hydrogen. Also your ECU has preset air/fuel mixes. so with the addition of more air you will get worse mileage due to more fuel being dumped in to compensate for additional air. I say its a no go. people will argue differently.

 

Cai for mpgs or power is pointless. It makes a cool sound, yeah but pointless.

As for my findings on mpgs from drum to disk, it's deffiney there. That is the only thing that changed..... I take that back. I did go ip in weight because the axle is much heavier.

The next few things to do is hook it to a vaccum gauge. Also look into your hubs and wheel bearings causing drag.

 

Alright im going to look at the drums, thanks guys, have any other ideas?

 

E-brake off?
rip in the intake?

 

The E-brake is off, how should i check the intake to see if there is a rip?

 

Yeah i checked the E-brake and it is off. How should i check to intake for a rip? would it be very noticable?

 

Make sure the e-brake disconnected from the rear drum...Mine would stick and I would have to take the wheel off and hit it with a hammer.

With my ATVs (never done it with a car) I would start the vehicle and let it run and then spray starting fluid all over the carb (intake area) and see if the RPMs changed any.

 

I had a crack in my intake mani gasket replaced it and still low mpg but being geared doesn't help either

 

Do you guys think that it being an Edge makes a difference? Because ive heard that Edges have higher 5th gears but around town I dont get into 5th gear

 

no
