Get to a mechanic ASAP for diagnosis and repair. If the CEL is flashing, have the vehicle towed
Have the car towed to a mechanic, do not drive it.
A flashing check engine light means that further running the engine may do major damage.
When did you last check the level of the oil, and did the engine recently over heat???
