I had driven about a mile away from my house when my truck started acting up. My check engine light started flashing, then the truck started woobling, then it started flashing: stabilatrak off and service stabilitrak. What the heck happened to my truck in that one mile? Well I pulled over opened up the hood and nothing seemed out of place. Shut the hood and turn the truck back on and the truck was still woobling. I drove about a block towards my cousins house, parked it, and got a ride from him to get to school.

I wont see my truck till tomorow so I have no way of getting in there and checking it out. What could be wrong?

I did notice that when I would put it in D it would go really lean and the wobbling would get worse. When I would almost come to a complete stop, it would also start wobbling really bad. I also noticed that when I would accelerate from a complete stop it wouldnt go forward like normal (like I was taking off slowly from 1st gear) and once I got to about 10mph it would jump forward like if i had floored it.?????

Anyone know what could be wrong?

 

by wobbling you mean the whole truck was shaking or the steering wheel?

pull the diff cover and look for debris.

 

What year is it? If it's DBW it sounds like TAC module went south or the harness for it got loose, or a bad TPS? Sounds throttle/computer related to me.

 

yeah by woobling I meant the whole truck was shaking not the steering wheel. (i didnt know how else to say it)

its an 09 rcsb silverado

 

i wont be able to do nothing until tomorrow afternoon

just wanted to see if anyone had run into this before so that I could get an idea of wat is going on

 

Can you tell if the wobble is motor related or if it's drive-line related?

 

Loose wheels ???

 

Torque converter went poopie?

 

thats the problem, it felt like a little of both. It would have a rough idle and once I would get it going the rear end felt like it was going to fall off.

I get what you mean but idk how it could be. I hadnt touched or driven the truck for 2 days since that afternoon.

probably, I just dont understand how it could of taken a crap without me doing anything to it. At least it would if been nice to say, "yeah I messed up my truck doing some donuts" or something, but it had been parked for a couple of days

for some reason, I keep thinking it could be the driveshaft, i dont have a reason though.

 

Kinda sounds like multiple problems them. The driveshaft and rear end arent moving at idle, so its not those, but they do sound like the culprit when you are moving....
