Flashing Check engine light is caused by a misfire. Its to alert you, that you need to get it checked out ASAP. there are a bunch of things that can cause a misfire on these vehicles: Distributor, distributor cap, wires, plugs, injector, cylinder head issues, etc...
You would simply need to have it diagnosed by a competent repair shop.
