2002 Honda accord check engine light on and blinks only at idle. Car runs fine, rough at idle. Low oil now corrected. What is it?

Missfire. Blinking indicates a plug, wire fault. Have it check to verify

Check for trouble codes first. When MIL comes on, they should not blink. Blinking could mean a fault in the wiring circuit.
