Will it do this when you are accelerating also or only when your foot is off the throttle?

the check engine light usually comes on when i just turn on the engine and disappears after about a minute or two(will try the five step method i saw on some reviews later in the day). initially, it used to go off like once in a long while, lately it became more regular. it goes off when i am in motion and my foot is on the throttle.

It could be something like a crank sensor intermittently dropping out but it will be very hard to test and confirm.
