Check Engine Light - Failed Smog. Received approval from AZ MVD to use their program whereby I was able to take my vehicle to a participating station (LeRoy's being one with the highest repair/pass rate), pay just $100 to have my vehicle repaired, and the state would pay the remainder (up to $900). Did that, Passed Smog re-test, and am good to go for another two years. Thanks to Troy and his team.
