Truck has the right ball on it.. I still haven't found out what is wrong with it. I'm interested in selling it and buying a Cummins and being done with these gas motors

 

The motor is not the problem!!!! The 35" rubber, and the 3:55 gears, are NOT "part of the problem" they ARE the problem.

 

Drop back down to stock height tires and the power will be there.

 

But then it won't look good with the 3" lift !!! You simply can't have it both way's without spending money on the gear's. Even a Cummins you are going to have some power loss, when comparing loaded and unloaded.

 

Listen, the truck did this before the lift and tires were on it. It did it with 265s on it. The TIRES are not the problem.

If the tires are the problem, someone please explain to me why it only does it when there is a load on the motor? I drove from Bay City,MI over to Silver Lake sand dues. Across the state... On the way there i had a quad in the bed, and had no problem. On the way home I had to pull 4 quads on a 4 place open alum. snow mobile trailer. Made it half way home until it started to act up again.

 

Try an experiment then. Put on the STOCK size tires, hook up your trailer, and have a go. Sure, it will look funny, but, Large tires, and low (numerically) gears add up to: Lack of power to move heavy objects.

Stock size tire is probably 245's. The 3.55 gears were too low from the factory. Dodge did it for one reason. Fuel economy. There is a reason trucks that are specifically designed to haul large amounts of weight, have stupid-deep gears.

 

Definitely does NOT sound like the tires. People are not taking the time to read your posts, they are just skimming, assuming, and posting before thinking. My apologies for the board.

Now, I'm not sure what you're problem is, but if it's running rich and burning fuel like a siv, the pre-cat O2 is a great pleace to start. You mentioned that you couldn't get it off to replace it. Use a cheater pipe or something to get that off. The O2 sensor coupled with the MAP and IAC determine the air/fuel ratio with the O2 being the most important component.

Focus on getting that thing off and replacing it. Use any means necessary.

 

And to the person that mentioned the trailer hitch ball, that is definitely a creative troubleshooting tip! These trucks don't have knock sensors though.

Creative nonetheless! I never would have thought to check that!

 

This is probably a dumb question but did you do a tune up? Usually when a truck starts acting up when it's under a load it's an indication of cap/rotor/plugs/wires. Could even try a new coil, just pick up a cheap one that you can mount on the right fender well. Dodge kinda had a $hitty design putting them on the front of the motor, gets all the weather through the radiator while driving.

 

^^^Good suggestion there too.
