Question about 2003 Hummer H2
Check engine light flashes on and off and the car loses power when this occurs generally only happens up a long or steep hill or at a higher speed.
When the check engine light is flashing that indicates an engine misfire, which is catalyst damaging. Because you said that it generally only happens up a long hill or at higher speed, and it doesnt happen all of the time, most likely you are in need of a full tune up.
