I'm on the highway going up hills. Everytime I drive my truck up a hill on the high way the service engine light comes on. Driving on a flat area doesn't make the light come on. So when i finally get to where i'm going and pull over, rev the engine for 10 or 15 seconds the light goes off. What is this telling me or what could be going wrong? I don't hear/see or feel any thing unusal when this happens. I tried driving it in the city going up hills and such, but it seems to be working perfectly fine even when the light is on. Anyway, should i be concerned about this or what? Any Help will be greatful. Thanks
