my mercury tracer is running rough and the check engine light has started blinking. the spark plugs look ok. changed the coil pack and plug wires 2 years ago.

The dealer of the car are the only people who cam pin-point the *exact cause of the flashing check engine light which could cause engine damage if you continue to drive the car.

The non-mechanics at Auto Zone do not have the equipment to pin-point the exact cause of the flashing check engine light.
