Hello, if the check engine light ever flashes it means the vehicle computer has a problem that can cause damage to the Catalytic Converter. The computer runs its own diagnostic ready tests during certain running times. But there should be a code stored in the computer if the light came on at all. It will go out if the computer can compensate for the issue enough. But it's not something you want to leave unchecked. If you go to your local parts store, they should be able to scan the vehicle for you and tell what codes are stored. Once you have the codes you can give them to us, and we can give you recommendations or you can take it your mechanic you trust.
There could be any number of different issues happening, low fuel pressure can cause this, multiple cylinder misfires, a bad catalytic converter. So, it's good to see what information is stored in the engine computer.
