FITV took a shit?

[1990HybridCB7]

I am pretty sure this is the cause to my surging problem, but just wanted to get a second opionion.

This all started happening after I did a head job on my car (H22). during warm up the car surges between 1500-2000.

When the car warms up, there is still suring when im in neutral, although, sometimes it will hold a steady idle but way to high (1500)

I checked and double checked my coolant level and made sure there was no air in the system, the idle screw has no effect. Didn't bother to check my IACV because I am almost certain the FITV is the culprit.

I believe it is the FITV because I followed the procedures for checking the working order of the valve in the Honda service manual and sure enough, after the car is fully warmed up, the FITV is still sucking air through the lower port in the TB.

One question I do have is how does a FITV go bad out of no where

everything was working perfectly fine before my head job, but now it seems that the FITV is done. Why is that?

Thanks for any help in advance.

open the FITV and twist the white plastic ring a few times to tighten it.

Never knew I could do that, it says in the manual that the valve comes factory adjusted and that it should not be pretty much tampered.

I just ordered a new one today

I'll try doing that before I attempt to install the new one and see if that fixes anything.

if the FITV is at fault, its because that loosened up over time. theres not much else inside of the valve that could just "go bad" ... it says dont adjust it, but it unadjusted itself.

flathead screwdriver usually works fine.

im guessing this is your issue

^^^^
I hope so... if that fix is the anwser to my solution than I'll be able to return this new part for my money.
