Recently bought a 2010 Acadia for my twins first car. The engine light was on solid. We ran OnStar diagnostics and also hooked the computer up to it and it said sensors need to be changed. Change sensors light got turned off but after sitting overnight, it came back on again. We were in the code again with a different code change all those sensors and once again turn the light off and it stays off and then it comes back on. Any suggestions please help should we run it more?
