Hello
Toyota Mechanic: carguy1, auto technician replied 5 months ago

The loose fuel cap will cause the check engine light to come on, but it won't cause it to blink. It also will take some time for the light to go off on it's own, but it can also cause the VSC light to appear.

The thing is, if the light is flashing or blinking, that usually is caused by a misfire. The misfire is the result of a bad ignition coil or spark plug most of the time. This is not brought on by the loose gas cap.

Normally if you have the codes read it will point to a specific cylinder and replacing the ignition coil will resolve the issue.

Please let me know if there is anything else I can do to help.
