just like the title, i was pulling out of my shop (being the parts runner b!&ch) and while i was pulling out, it spit and sputtered and then backfired, so i let off the gas and got back into it and then it felt like it had tons more power than usual, i know its not the best description but i really don't know how to explain it, could it be that my fuel return line is rigged up to the broken rollover valve? what does the rollover valve do, and where can i get the diagram on how the fuel lines run so i can replace them? can i use high pressure rubber hose?
please help me im stumped, and i feel as if this problem has started to happen more often then it used to. one other thing, what does it take to pull the bed, mine is pretty rusty found a cheap one on cl in ashland from that dodge parts guy ( he is a great nice guy, i recommend him to anyone and everyone who lives in the area and is looking for quality parts). and one other thing, while i was working on ctd project, i had found out that i had to use a lsd supplement to thicken the oil? would that be the same for mine? the ctd has a dana 80, im pretty sure i have a 44? not sure, but was wondering if the stuff loses viscosity, and would it cause my rear end to have only the one tire spin, for example, if im going up a steep hill from a stop sign, if i get into it to early ill break the passenger tire loose and have to let off and granny foot it up the hill.

im sorry this post is so long (and poorly punctuated, lol, this is all stuff that popped in my head when i jumped on the forum, and decided to post it, cause i know there is a lot of smart folks on here, love this forum will never use another.


thanks in advance guys,

Possible clogging cat, or failing O2 sensor. There is no return line on the fuel system on our trucks. If you think you have a fuel pressure problem, put a gauge on it, and see what it's doing.

Rollover valve is exactly that, if you roll the truck, it shuts off fuel flow.

You have a Corporate 9.25 in the rear. D44 in the front. If you have an LSD rear, you need the friction modifier. They are famous for tossing the clips that hold the clutches in place, which eats the rear.....

 

so, what is the 9.25, a very light duty? like i cant haul a car on a trailer safely? i buy cheap cars every so often when i need money and turn around and sell them for scrap, but i have always used my pops truck, which was a 98 1500, with the towing package, and i pretty sure it had a beefier rear end almost looked like it was a d60 like in a 2500, and it had 4:10's, now i have 3:55's which i hate, want to upgrade them for either 3:73 4:10 or 4:56, but im not sure what to buy and i have a limited spending range, could you give me some ideas on prices for both axles. i know i could look myself, but i would really like to know your guys opinion. and yeah, the whole think you were talking about for tossing a clip and eating up the rear, ha i have already been through that on my dads new truck ( of course its my luck that it locked up when i was driving it, and every since we had to split the cost on a brand new rear end, i haven't been able to drive it lol), but anyways like i was saying with my rear diff, will the friction modifier somewhat help the whole tire spinning thing up hills, or is that just because i have a moderate heavy foot. let me know.

 

9.25 is a pretty nice rear. The posi units they used in them weren't the best.... as you noticed. All the half ton trucks came with 'em. Don't get into the D60's until you go 3/4 ton truck.

Hauling around a car on a trailer should be fine. Check the sticker in the drivers door frame for GCWR. That's the max that truck, and cargo should weigh. It isn't so much a product of how much the truck can pull, but, how much the truck can STOP. Exceed your weight rating by too much, and you will find the trailer pushing you thru stop lights and such. Never a good scene.

As for gears, what size tires do you run, and do you want to go larger? The price really doesn't change very much with the ratio. If you have to pay someone else to do it, anywhere from 1200 bucks and up... depending on labor rates in your area. Just parts are going to run around 500. (gears, and install kits.)

 

guy around here had the same problem. it was the O2 sensor. I forgot which one but that was the cause.

+1 on clogged cat or bad O2 sensor. Pull out upstream and see if problem goes away. If so, replace cat and get new O2 sensor also.
