i have a 04 SE with 76,000. i have had the truck since new always loved the way it drove. since last week the truck feel as if i'm dragging a dead elephant. i put it in neutral and it rolls fine so its not a locked rotor or a bad axle bearing (yes the seal leaks). the engine seems fine, no check engine lights, always use premium gas. i have done all the recommended service. im due for an oil change, transmission flush and just changed the radiator cap and air filter. the manuel does not call for a "tune up" ex plugs wires....

has anyone done a major tune up?

Are you sure it is not in 4WD?

Is it slow on exceleration? could be the cats are clogged

Could also be a frozen e-brake line.

What's the gas mileage?

What does it do when you "goose" it? Do you run a K & N? And if so, oiled it lately?

And possibly reset the ecu?

there is also a tsb on the fuel pump that would do this.

He has a rear axle seal leak. Maybe the rear end is going and only puts up resistance under load.

Also wonder if his tranny has ever been flushed/serviced?

Guys im clue less. the truck does not feel as it is misfiring or bogging. it just feel really heavy. it has a new stock air filter, the trans fluid was changed at 36,000, due for another. my milage has dropped. listen if i stomp on it it will go, the problem is under mild acceleration. this truck has always felt like a race horse. it use to almost never down shift even if i was asking it to go. now up mild over passes when i give it alittle more it downshift. guys it just feel totaly different! i'm out of wrnty and don't was to go to the dealer without narrowing it down. i'm going to get raped!

Im not crazy i have been solely driving this truck since new, something is going bad!

I think I would do a ECU reset as stated above. Unhook battery, open drivers door to kill any stored power, wait about five min or so and then rehook bat. Crank truck(may idle a little weird at first, but let it warm up on with out interference)(you can use this warm up time to reset the radio stations and radio clock) If the trip odo doesn't read 0, it didn't reset. After warmed, go out and run it like a dog. Find somewhere you can stomp it up to about 75 or so. Do this about 5 times. Shut her down, go to bed or work or whatever, and see if this issue improves. If not, bite the bullet with the dealer. GOOD LUCK and let us know if this works.

Sorry i took long to get back to you, had to go to Naple, Fl (obviously not in my Titan). i tried what you said and i'm happy to say the race horsce is back!
Now what's the ecu? could i have cause this? i did something different, last Saturday i pulled my new to me 23' open fisherman apprx 4500 on a trailer i just re-bulit. since i was not sure of my work i towed slow 55 in D and the truck felt like **** 20 highway mile each way. mind you 10 months ago i trailered a wrecked BMW on a uhaul dolly from the mountains of Tenn. to Miami @ 75 in D like nothing.
i will be pulling the boat again tommorrow. i don't think its heavy enough for 4th so i will pull fast 70 to get my rpm up close to 2000.

Thanks for you help keep your fingers crossed!

Good to hear you got it fixed John....
Are you from Tenn.???

No i'm in Miami Florida. i hope it can pull tomorrow. my boating buddy has a 1989 Chevy 2500, boy did he lay into me about how poorly the truck pulled. Guys remember i'm at sea level no hills.

As far as you causing it, inadvertantly. The computer(ecu) self learns driving styles for power, fuel efficiency, etc. If you have been babying your baby for the last 5 or so drives, it stored the "babying" as what you wanted long term. That's why you do a reset. It's either do it that way or waste a bunch of gas driving the dog out of it for the next five key cycles(learning mode of ecu between crank and shutoff). It's a pretty smart truck, huh?
