Default HELP: Surging Idle

So i start up my beater after months of letting it sit in the garage. It starts without a hitch but about after 2 minutes my cars idle started to surge. No Cel, Hmm so i searched and found out maybe it was a dirty iacv so i cleaned that, didn't work. Flushed and bled the coolant, Nope not that either. I'm not sure what else it could be? Anyone knows what it could be? only happens when my car is warmed up and on park.

BTW its a d16y7

its more than likely your Fat Idle Thermo Valve.. follow the link THC07 posted and retighten the plunger inside of the FITV..... if that doesnt work eliminate it all together. you can just make a plate out of real thin sheet metal and put it between the FITV and the throotle body...

but if it's a vacume leak shouldn't it be happening right after start up? i mean it only surges after 5 minutes of it idling. Basically when its warmed up.
