Check engine light on all the time!

What is your question?

Hi, I have a 2008 Sebring Convertible w/4 cyl. engine. Failed Massachusetts State Inspection for emissions. I replaced gas-cap w/Mopar correct cap, "Check Gas Cap" light still comes on. We had code P457 come up, and that was addressed and fixed with evap plug and replaced leak detection pump. The 'dealership' (mom and pop place) told me to drive 500-600 miles on the fixed parts and the light should go off. I have gone over 650 miles, light still comes on and code is P10000 now. Running out of time to get the car fixed and to pass inspection. Thanks! Todd G
