B18c Rev Jumping

[xxx26e]

Hi all,
I am having a problem when the car warms up.
When the engine is cold and until the temp guage is in the middle,
the car revs at 3g's and then starts jumping between 2 & 3.
When it starts getting towards the middle it jumps between 1 & 2 g until
the revs normally.
I just installed a Blox intake manifold and CAI.

Whats Could be the problem?

is it still using the old IACV? Or FITV? If so, clean and adjust maybe? is the TPS calibrated?

Yeah i am using old IACV and FITV.
I am cleaning IACV now
And no TPS is not calibrated? How do you do that?
What does FITV stand for?

Cheers

Just cleaned it and made no difference!!
Could the valve be broken?

Stands for Fast Idle Thermo Valve, and in terms of the TPS, http://www.ozhonda.com/forum/showthread.php?t=120191
