Electrical problem
2004 Mazda RX8 Two Wheel Drive Manual 31000 miles

it starts and runs fine, but when driven after about 5minutes the check engine light blinks at random RPM's but still runs fine. Then at idle it stops blinking. Tried coils those are new. And the plugs are new also. What is wrong?
