Lately my 06 ss bogs when floored going from a roll. Traction control is off. Say I am going 15mph and I floor it. My car will. Take off quickly but almost imedeatly it will bog down. And then go take off . Some times it will bog....go....bog then go again. Please help. Plugs? Tranny? Somthing else? I changed the trans fluid to see if that would help. And nadda. Also is it normal when I floor it that my car won't downshift first at WOT?

its drive by wire throttle, right? if so, I'd look at replacing the throttle position sensor.

My 10 impala 3.5 does this. It sucks.
