When the check engine light comes on, it indicates a potential issue with the vehicle's engine or emissions system. A stall at a stop sign could be caused by a malfunctioning sensor, such as the mass airflow sensor or throttle position sensor, which disrupts the air-fuel mixture. Additionally, a failing fuel pump or ignition system component might prevent the engine from restarting easily. It's essential to have the vehicle diagnosed to identify the specific problem.

If you need an inspection, then unhooking the battery for 5 minutes and driving maybe 20-40 miles and then going for inspection may do the trick. There is a small window where the check engine light hasn't come on yet and the IM monitors are mostly ready for inspection.....just before the check engine light comes on again. It will pass, in this window. But when the check engine light comes on again, it will not pass.
