Ok i have a 2011 Silverado, and I was wondering if anyone has this problem,
Ok when I slow down coming to a stop sign, but don't come to a complete stop, but I'm braking, then step back on the gas its like it bangs hard it dosen't pull off smooth,,
It feel like thers a void, or some thing,, also the rpm dosen't come back correctly, Like it drop down to 600 and then goes up to like 900 and then back againg to 600 any Ideas,,,,,,
also it dosen't matter what tune I'm using even stock,,,
Any one have the same problem
My 2010 Colorado does the same thing. It's the electric throttle. (Look Ma, No Cable) what you are experiencing is the slight lag between what you do with your foot and what the ECM tells the throttle body to do. Your coices are to replace the ECM with one that uses a throttle cable or do what I did. "Just live with it." You will eventually learn to compensate for most of it.
