Hummer h3 almost wanted to bog out at a stop sign this morning. Was kind of jumping forward when I took my foot off the brake. Codes that followed were p2101 p1516

Answer 1

P2101 Throttle actuator position performance

P1516 Throttle actuator control (TAC) moduel throttle actuator position performance

With these 2 code the vehicle can go into a engine reduce mode. When either of these code are set the throttle body blade opening gets binded, start with a throttle body cleaning ,
