found it out. the accelerator pedal position sensor had a bad connection. i unpluged it and plugged it back in and truck runs just like new. also got error code p2138 just in case it happens again save ur money and look for loose connections on any wire connection. GOOD LUCK. im glad i had friends in good places.

I had this problem this past spring and the dealer told me he had to reprogram the transmission. It went away and ran great till about 2 weeks ago and the same problems arose. I'll try looking for the pedal position sensor. Where is this sensor located? Wish me luck

the sensor is located on the foot pedal itself. u cant miss it u can see the wires running off of it. if the engine light stays on after its fixed, disconnect the battery and it will reset itself. DO NOT PAY FOR THIS, IT CAN BE DONE WITHOUT BEING HOOKED UP TO MACHINE!!! dealers dont know shit are nothing but ripped off artist.

I am having the exact same problem and my delaer cannot find this document. Can you please verify the document number or let me know what dealership you went to so they can call? This is very frustrating.

After repalcing two relays and other BS we have determined that the body control module that the autoride suspension pump is controlled by needs reseting. Is this a dealer only procedure or can I do it myself without going to Mr. GUTWRENCH!

Had to replace front differential. Vehicle was only serviced by GM dealer and I told them on two ocassions there was a noise in the car. After the car was out of warranty the noise got worse. I went to AAMCO and they replaced the front differential and the vehicle is quiter than when the car was brand new, AAmco said there was hardly any oil in the case. GM paid for 75% of my cost and was just told my rear differential is leaking. This vehicle is kept in a garage and there is not one drop of oil on the floor. Could this be a factory goof? Whoever changes your oil insist they check both differentials and the transfer case and have it noted on your work order. Also had a $600.00 transmission repair when just out of warranty
Vehicle was only serviced by GM garage and I complained about noise on two different ocassions

I had a similar problem with my 2004 yukon denali xl. It died 4 times in the first 6 months of owning it. It was in and out of the dealership with all kinds of repairs, reprogramming and replacements in addition to an examination by a special GMC engineer. Even he couldn't determine the cause of the problem. I finally wrote a letter to Rick Wagoner since I was getting nowhere. After that, the dealership conveniently determined that the problem was caused by the aftermarket DVD player that was installed (at their recommended shop). I was so fed up, I turned in the truck and got a 2006 model... guess what, it's starting to do the same thing - but no after market DVD player this time. So frustrating - crap car, no wonder they're going bankrupt!
