To address the check engine light, you need to have a diagnostic system check of the powertrain. This can be done at most auto part chains. Regular occurrences involve a faulty catalyst(P0420/430), vent system performance(P0446), or oxygen sensor heater circuit faults. As a primary visual you can do yourself, check that the fuel cap is fully installed.
