Surging while in 4wd low when taking off.

[TrailChaser]

I first noticed this problem last weekend while at the beach. What happened is that I parked the truck close to the water and we went for a walk. When we got back the tires were in the water a little from the tide comming up. We got in and it was digging down in 2wd so I shifted strait down into 4wl. When I gave it a little gas it surged about 3 times all by itself. Just like if I were to punch it and let off 3 times real quick. Had me freaked out, but everthing was fine after that.

Then today we where back at the beach and I stopped in some pretty deep sand. When I started off it did the same thing...

Anyone know what this could be? I'd hate to have it do this crap on a hard trail.

 

One more question... Can you get an idea of how hot the tranny/transfer case is by touching the shifter for the T-case?

The reason I ask is that I've had a habit of checking to see just how hot it is. Before I put the tranny cooler in it would get too hot to hold on to for more than 10 seconds, but now it never gets that hot. It goes from pretty warm when I'm in stop and go traffic and red lights, but on the highway it gets really cool.

 

Here's a couple of pics of the shells I found on the beach. Those are last week and this week combined.

Was the engine warmed up or cold when it did that? Nice shells, man.

It was warm. We had been riding around for quite a while. It also does it when I punch it from a stop like at a green light. Thing is, I've got the pedal down so it's not the same. It's more of a slightly losing power 2-3 times right after I floor it.

 

I just found out about this thanx to some asian woman being a dipstick and pi$$ing me off enough to floor it even tho gas cost more than milk. I usually drive like an old lady solely because it cost $40+ to fill up the tank.

Thanks for the comp on the shells. I should've takin the pics outside so you can really see'em.

Oh, we NEVER find shells this big... This is because of the recent hurricanes. I've found two so far that still had the citter inside. I left those alone. I wouldn't want some dude to rip me outa my house just so he could put it on a shelf.

Because it is mainly 1st gear, I say check your motor/tranny mounts. Best way is to watch the motor with the hood open and someone giving gas and standing on the brakes at the same time. If the motor lifts too much, investigate further. The motor could be moving and pulling/relaxing the throttle cable which will cause surging. Check it out, its free. I'm assuming you have run the ECU codes already... Nice shells by the way !

*UPDATE*

 

Cleaning the MAF sensor seems to have solved the problem. Along with the crappy pick-up and crappy idling problems I didn't know I had till I cleaned that darn thing.

 

Thank you VERY much for the write-up on that subject 88 it helped out soooo much.
