Misfire
Faulty: spark plug, spark plug wire, ignition coil, ignition module, fuel injector are the
most common. Coolant leaking into a cylinder is another.
Internal engine problems such as burnt valve, broken valve spring, bent push rod, worn
rings
You have to find out what is causing random misfires in the engine. See related question below.
start with new plugs
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.

The check engine light on a Mazda Tribute gives warning of potential problems. It can signal overheating, low oil, or engine misfires.
How about the plug wires? If plug wires don't fix it I'd bet it's the injectors.
not necessarily unless after replacing plugs your engine misfires.
