Default Cold start and idling funny every 5 second or so

I've been having this problem with my car. On cold starts the car idles smooth but every 5 second or so it dips so it idles like this:

-----------v----------------v--------------v

When it's warm the problem goes away

BUT yesterday when climbing a long hill it bucks back and forth and then goes away after (not sure if turning off the AC helped that)

I sometimes feel the hesitation when accelerating too.

I've done:
Cleaned maf
New plugs
New coilpacks

TGV deletes will do this until the car warms up. Do you have them deleted?

Don't think so. Don't even know If i have them. It's a JDM car.

Right now the car is doing this even when it is warmed.
