At idle it feels like it has a small cam and the exhaust sounded different too
Once I get the truck moving, thats when the rear end starts to go crazy
5 more hours until I get a chance to check it out, and hopefully it wont take away too much money from the money ive been saving for my swap.

 

Maybe a rodent go up in your truck and chewed on some wiring?

 

Maybe not a rodent, but maybe my dog since she sleeps in the garage with the truck...

what wires would give the truck a rough idle, a shacking rear end, and make it flash service stabilatrak though?

 

This is what I was thinking...see it at work all of the time...

 

I just spent 4 hours in my garage splicing and soldering about 12 different type of wires and power chords that belong to a friend of mine who's dog just went to town on her Entertainment system wiring. Everything from the Wii, PS3, cable box, TV, etc... was chewed to ****. So it is possible, what it could be...there's alot of possibilities. I would suggest checking around the PCM first and then anything that either hangs low or is near a heat source since a rodent would go what nearest the heat source anyways.

 

sprak plugs, a loose wire????

 

If the check engine light is flashing it means that you have a catalyst damaging misfire in the engine, also this will cause the stabilitrak to be disabled causing the lights to come on. If it is an 09 why dont you just call roadside and have the dealership fix it???

 

Well I had to work late and my cousin got his hands on my truck first. He drove it back to my house and it was still doing the same thing. He parked it outside, went inside my house to open the garage, turned the truck back on and then suddenly it went back to normal. The check engine light was still on so he scanned it and he said that 2 codes popped up and both said RANDOM MISFIRING. I drove it around for about 40 minutes and it feels normal again, though it still feels like there's something there but thats probably just my imagination.

Really? What exactly is that? I wish I could just take it to the dealer but I've had it tuned already and the guys at the dealer are so quick to void your warranty that im hesitant to take it. Now that it seems like its back to normal, whats the worst that could happen?

 

Your truck is haunted!!

 

not again
