2011 5.3 Missing?

[cameronc]

I just bought a new 2011 truck with the 5.3 in it. I have been in love with this motor since it hit the market and have had great service out off them. My new truck now has 500 miles on it and I have had a problem since it was new, It has a miss/hesitation when it is cold. Once it warms up the miss goes away but still has hesitation sometimes. I thought I bought some bad gas at first because it had alot of condensation coming out of the exhaust on first tank of gas and now has gone away after second tank. I thought it may have had some water in it but it still misses when cold. Just came from the dealer and they said there was nothing wrong with it because the check engine light wasn't on & they couldn't find anything wrong. I cant explain why the light doesnt come on but I know it is mising, i can feel it, it almost feels like it is cutting down to 4cyl mode when cold. Can someone PLEASE HELP me. Thanks Alot Guys.

I even call General motors personally and complained, they worked with the dealer on the truck and come to the same sonclusion. I have had it to two different dealers. GM finally called me and told me to just run it until 5000 miles and if it was still doing it then they would look at it again. Bullcrap, basically GM just told me to run a faulty unit until something blows. I am disgusted.
