Hello, my name is***** the check engine light flashes that means you have a current misfire going on. Next step is to have diagnostic codes checked which can be done at your local parts store for free. It should indicate a specific cylinder, the most common cause is a failed ignition coil. You will want to swap coil on that cylinder with another cylinder then have codes checked again to see if misfire follows coil, if so replace. This would be about a $250 job to have done at a shop. Let me know if you have more questions or if there is anything else I can do to help. Thanks.
