Hello my name is XXXXX XXXXX Thank you for your question.
If the Service Engine Soon light is flashing, that is a bad thing. If you continue to drive the car it can cause engine damage.
That is what that light means when it's flashing
If it was just on, then it would be safe to drive.
My recommendation is to have the car scanned to see what codes you have.
It's most likely a misfire code.
Which can be caused by a few things
Clogged Catt Converter, Bad Battery ground cables that burnt out the coils and Ecm, or simply Bad Plugs or Injectors.
You will need to have this checked before you do any real engine damage.
If you have any more questions on this, please feel free to ask.
If not, and your satisfied with my help, please Rate me. I hope I have provided you Excellent Service.
