Thread: Need help with GTiR idle issue... Please confirm/crush what I'm thinkin'

Just swapped a GTiR into my B14... First startup acted fine at first. Pulled on the throttle a couple of times w/ no issues. Pulled again and it came up to 4000 and stayed there. Now, when I start the car it climbs straight up to about 3500 and holds.

I disconnected one of the plugs on the IACV and it did the same thing... disconnected the other plug (grey round one) and it started jumping up and down like it has a vacuum leak.

Any thoughts on what the issue could be or what I should check?

Nevermind... something is going on in my tune... I just realized that the fuel cut flag is blinking with the fluctuations in RPM... gotta dig into nismotronic...

Closing thread. Discovered it was the ITB being cracked open.
