Blinking means that the control computer has detected a relatively serious problem. You should connect to an OBD2 diagnostic scanner and find out what's wrong, and do it soon before something is damaged.

Many auto parts retailers will allow you to use a scanner and often someone will help you connect it and read the results.

Normally a flashing check engine light means you have a misfire. Do not ignore this as an engine misfire will damage the O2 sensor and the catalytic converter which are very expensive to replace. Have this repaired immediately.

Ford Explorer service engine soon light?

When the service engine soon light is blinking, it means a subsystem of the engine has failed. It could be something as simple as a broken gas cap, or it could be a serious engine problem. If the Explorer is still running fine, it is best to get the codes read at an auto service shop to determine the next course of action.


When you drive over mph that's when the service engine light starts blinking?

On our 2000 Silverado 2500 the blinking can mean a misfiring cylinder or ours also does this from "extended" periods of high RPM operation, like when driving over 70 mph. I feel our truck is especially sensitive to this because the rear end has the 4.1 gear set, I have often wondered if a truck equiped with 3.73 ratio or 3.42 ratio would still do this.
