    When the Check Engine light flashes it means the engine has a bad enough misfire or condition to cause catalytic converter damage. You need to get this straight to your auto technician. Could be a lack of fuel pressure or an ignition problem but your auto service facility should run a thorough diagnostic test to determine the possible root cause(s).
