Throttle body woes
I've been trolling around looking for some answers, '11 Silverado CC 4x4 LTZ 5.3. Dealing with throttle body issues. I want to replace it, the dealer replaced it once already, it only lasted 8 months/6-7k. Extremely frustrating just looking for a better unit any suggestions?

If it is the throttle it is covered under warranty if you are under 120,000 miles. An alternative would be to swap to a LS3 90mm throttle body. http://www.ebay.com/itm/2009-2010-Chevrolet-Corvette-Z06-Throttle-Body-LS3-LS7-GM-12605109-/350927333470?hash=item51b4e6285e&vxp=mtr

Stability control came on, traction light, reduced power, all at highway speed slowed the truck from 65 to 35 in a really big hurry, not fun. Dealer cleaned it, good for a month maybe. Did it all again and they replaced it for $600. Not even a year later it's doing it again.
