Virginia's Department of Agriculture and Consumer Affairs confirms for NewsChannel3 that it is testing gasoline from across Hampton Roads to see if it contains too much ethanol.

More than 10% ethanol in gasoline can cause your car to stall, backfire, not even turn on or at least cause the check engine light to come on.

If you've had any of these issues with your car in the past week, call the Department of Agriculture and Consumer Affairs Hot Line for gas with elevated levels of ethanol at 804-786-2042
