2007 Tahoe - started to jerk/slip when accelerating

[Seacow1]

Hi all -- Im new here. I just had the front brakes and rotors on my 2007 Tahoe replaced and now when I drive it feels like it slips or jerks when accelerating--from braking to foot on gas. It may be a coincidence that it happened right after we had the brakes replaced, but I am curious to know if something could have been bumped or triggered on the 4-wheel drive? Or maybe the brake and rotor replacement tripped some module? Any insight or thoughts would be great. I just dropped a cool $900 already and would prefer not to drop another if it's a simple fix.
