Reduced Engine Power, Service Stabilitrak, Service Traction Control. Only happened after cruising down the interstate for over 2 hours. I understand the truck throttle bodies have problems at high rpms in a boosted application, but this was occurring below 2000 rpms. Any thoughts? I know the NBS trucks had some connector and/or harness chaffing problems or carbon buildup with the throttle position sensors. Is this still a problem with the NNBS? Truck only has 36K and does have a catch can.
