Cold Surging Idle B18C-R
I have a 92 hatch with a 96 spec B18C-R and I am having a surging idle problem only when the car is cold. These engines do not have a FITV, and my coolant levels are fine..
When the car is cold, it'll go to a very high smooth idle, around 2500 rpm or so, but if I even touch the throttle it will begin to surge from about 1400-2500 rpm. Once it's warm the idle is smooth at around 900 rpm. I can restart the car as long as it it still warm and the problem doesn't come back, unless of course I wait until it gets very cold again.
Any help on this problem? If I had a FITV I would say that is almost for sure the problem.

It's the IACV! cleaning it sometimes doesn't work. try another one.
