the pulsation occurs when applying brakes to stop and the check engine light is on or it blinks on and off.

    Sounds like 2 differant problems...pulsating when applying brakes typicaly means you have warped brake rotor disc and a flashing check engine light typicaly means the computer is detecting a miss fire in engine...that could damage catalytic converter if it not repaired.
