Okay I have a 2002 DC5R.

Crank the car and it's fine, idles around 1300 or so.

After a minute or two of warming up, the idle starts to surge between 1-2k and won't stop.

I'm away from the car so I haven't checked if it's starting to surge when the thermostat opens or not.

Could the map sensor have gone bad? Coolant was just bled(again) and there are no air pockets. I'm a Honda rookie so I'm kinda in the dark. I talked to a buddy who said something about possibly being a barometric sensor which is located in the ecu and having to take it to the dealership?

any help would be greatly appreciated :/
