idle surge IACV symptoms

This is for anyone else who has dealt with the same issue I have been dealing with for the past year. After checking for Vacum leaks, ECT sensor and cleaning the IACV , finally had to replace it. (OBD 1 code P14)

Check this link out.

if you replaced it and there's still a problem.. with no leaks evident. (make sure you've reset your ECU after replacing it)... but if you have done all of that, still throwing the code, all you need to do is most likely drain the air out of your coolant.
How to do it:
from cold start, have the rad cap off, run the car til the fan comes on at least once (make sure your heater is on inside the car), watch the bubbles come out the top of the rad, then top up when needed. once the ran fan has come on at least once and you are satisfied that the bubbles are done, crack the bleeder where the top rad hose enters the block (14mm I think). then reset ecu. And voila. no more surge.

Still waiting for the part to come in. Tried cleaning 2wice and still no luck. Hopefully this used one is ok too. Off a b18c5 mani.
Has this happened to you?
