I just got my f-150 fixed with that same problem. I replaced the spark plugs and spark plug wires. The blinking check engine light is caused by excess gas coating the catalytic converter sensor. If left unfixed this will cause permanent damage to the catalytic converter.

My check engine light in my 1997 cavalier blinks then stays on steady what is the problem?

Numerous things could cause this problem. Most of them are nothing to worry about. As long as you are talking about the AMBER "check engine light"... Since it blinks, I would check with a Dealer first. The blinking indicates a possible future problem. Once it is steady, the car has identified a problem. One thing to check... Make sure the gas cap is tight!!! No idea how the car runs or idles, so difficult to figure...bring it in.
