08 Impala LTZ Acceleration Issue

Hey Everyone,

I have a 2008 Impala LTZ with the 3.9L and I'm at around 85,000 miles. When I'm cruising at highways speeds and I slightly accelerate to go up a hill the car seems to jerk back a few times almost in a bucking motion before finally smoothing out and speeding up. The check engine light has not come on and the scanner at autozone did not pull any codes. Is this just a symptom of a bad spark plug or could it be something else?
