mine pops and idle wanders a bit once its warmed up but its not the iac because it works perfectly at other times
check for air leaks and possibly change the coolant temp sensor and the lambda sensor and see if that cures it

have you tryed simple things like fuel filter and plugs ect?
nah its not a normal problem like plugs, as ive known of other 16xe's that do it.
i have noticed a air leak sound at high rpm, also thought it may be the exhaust blowing!
just seems like a sensor or along that lines as it realy does hold back at times! looked at the plugs etc yesterday and they seem pritty new, ngk twin tip things lol will have to give it a good going over at the wk end :roll:

mines always had a flat spot around 3-3.5k
most noticable at part throttle, even the exhaust note changes as it goes thru it
it goes away a little if i run it on optimax and reset the ecu
and goes perfectly fine above 4k
