VSC and Check Engine Light
VSC and Check Engine light came on this morning when I started my ES350. So I checked the gas cap and it was opened, so most likely I didn't tightened it well after putting in the gas yesterday.
After I tightened the gas cap and started the car again, both lights are still on. I drove around the neighborhood and the car feels normal (no vibration) to me, but the lights remained on. Do I need to drive the car a few rounds to reset the light? But I also worry about something else aside from the gas cap is wrong. Any suggestion?
