Why does your 2001 Mazda melinnia check engine light keep flashing?
A flashing check engine light means you are doing serious damage to your catalytic converter due to repeated misfires in one or more cylinders. If you get a code scanner (or go to an autozone, oreilly's etc. where they scan it for free) you will see a code such as P0301 (misfire, cylinder 1). Your catalytic converter is probably shot now. If it is and If you live in a state that does emissions inspections you will need to get the converter replaced after you fix the misfires. An old spark plug will generally cause the misfires.
