Changed a pulley now check engine light is on!?!?
I recently for my idler pulley changed(the one that feeds the belt) and now my check engine light is on!!! Does anyone know what might have caused this? The car runs and sounds a lot better but the light won't go off.

I say check vacuum lines, you probably knocked something lose and have a vacuum leak. Get some propane, brake clean or wd40 and start spraying around the engine looking for a rise in idle.
