Engine/drivetrain issue??

While cruising at about 2000rpm on steady throttle, I noticed that the car does a tad of a jump. Feels like one would tap on throttle every 2 sec. The rpm's don't go up or down. Any ideas??

Recently changed serpentine belt and Vanos solenoids. No codes on BT tool. It's an xi. Transfer case was replaced two years ago.
