It means damage to your catalytic converter is occuring. If your car is running rough and has no power, check your crank position sensor before you dump a bunch of time and money in it.
On Mazda's, when the check engine light is flashing it means you have a misfire. The most common causes are the ignition coil packs or spark plugs.
