Just purchased 2016 2.8 Duramax Z71 with 133,000 miles. First trip out of town yesterday, no load or trailer. Halfway up a steep grade, "reduced power" warning displayed along with check engine light. I pulled over within a mile & shut off truck for 5 minutes. Warning disappeared but check engine light stayed on. Truck seems to be running normal now. After doing ECM check, fault code P2263 "turbo boost system performance" is displayed.
Is my turbo fried? I looked under hood & noted 2 white lines on waste gate actuator & they do not line up, engine off or at idle. Could this be part of my problem?
