Way to go---score one on the system!!LOL. My mechanic says the engine light problem is a 'soft code' and is more of a costly nuisance and nothing I need to worry about. In PA you can't get the emission control part of the inspection passed with the engine light on. So when I take it to the shop to get it inspected I disconnect the battery and rehook it back up. That resets things long enough to get the emission control passed before the light goes back on.
