Rough idle then a bad miss with blinking check engine light

Hi Everybody, I'm planning to replace coils and plugs this weekend, but I realized one tiny factor. I only get that sputtering when I hit the accelerator. If I let go of the accelerator, it runs smooth. Still an electrical problem or possibly gas flow ?

Being you are already planning to do the plugs and coils I would say replace them Your expy most likely hasn't had them changed in a long while
