Just dusted the Jordan off after being sat for 18months to get it motd. I have a bit of an issue with slightly raised CO emissions (couod just want a new cat, could be relatd to the hunting) and it hunts a little whe you try and hold a fast idle at 2-3krpm.

Spec is:
AEM long intake
Std throttle body (i also have a pro power and 68mm skunk 2 i can try)
Skunk2 intake with ported plenum / runners
K20 injectors
Lightly ported and skimmed head
Buddy Club spec 3+ cams
Itr dc2 springs and retainers
DC Sports manifold
Spoon b pipe
Mugen twin loop silencer
Neptune RTP doing the thinking.

Any ideas where to look for this hunting issue?
 
Isn't hunting usually down to the IACV or throttle position sensor, or a vacuum leak? typically the IACV i've heard
