    Poor mileage after Manifolds replaced

    Mine were replaced last July with the current part number, mpg hasn't changed

    Frustrating on/off P-0440 code

    On my previous truck, I used air (low pressure, maybe 10lbs) and then looked for the hiss. Found cracked/rotted hoses connected to the ESIM and and charcoal canister I've dealt with that code on my previous truck and it is frustrating, I'd buy a smoke test machine if it happened again...

    What did you do to your Ram today???

    Yes but my interior is indigo/frost so that part would stand out badly or I'd have to paint it

    What did you do to your Ram today???

    Epoxied up infamous broken sun visor I don't need it to rotate, just flip up and down. Called a local dealer for a new one, $81 online and he had it in-stock but I'd have to wait til tuesday. If I came in to pick it up today, it was $182. Me: So you have it in stock but its $182 to pickup...

    Lol, no and no need to justify my 3.21's. They do exactly as I ask, tow when I need to and get the best mpg possible when I need it to, they'll even pull your girlx4 out of a ditch when you get stuck 😄

    This thread spun off the road 3 years ago; 4x4, 3.92 nor the mighty trx is getting us out of this ditch🤣

    An Engineer's Ultimate Guide To 3.21 VS 3.92 Axle Ratio

    Yeah and it sounds like you're talking about a 90's-2000's lincoln with a 4 speed, not a modern car with a modern 6, 7, 7 or 10 spd trans so not a valid comparison. If you're driving a 4x4, stop crying about the mileage, you knew that when you bought it and your 4x4 is doing the same thing my...

    An Engineer's Ultimate Guide To 3.21 VS 3.92 Axle Ratio

    I partially agree, around town the 3.92 truck "should" get better fuel mileage for the simple fact that the 3.92 should be a bigger better lever for moving weight. The only problem with that thought is that damn near all the 3.92 people that care about mpg complain about the 3.92s economy on...

    An Engineer's Ultimate Guide To 3.21 VS 3.92 Axle Ratio

    You're comparing a car to a truck, another car setup the same but with a numerically lower gear will have better mpg. No different than the trucks here now. At 60-65 mph, my 3.21 gear'd truck is indeed lugging and fuel mileage is around 17-18 mph but thats about 1300-1400 rpm, too slow for an...
