wtf? IACV making noises???

i turn my key on to prime the pump and leave the key there you can hear the IACV making a low humm/buzz... IT ONLY HAPPENS WHEN MY USDM P30 is plugged in.. when i plug my chipped P05 in it doesnt do it... i have never had one do this before.. or at least never noticed it before...

P30 does it with the chip, and with the jumper cut... (for some reason i cant get any chips to work right now, just getting solid CEL)

oh i also unplugged the IACV and it obviously stops, and plugged another one in and it would do the same thing...

your thoughts???

Re: wtf? IACV making noises???

trying to set airflow for high idle.........

what you thought some little gremilin in the ECU did all that?

Re: wtf? IACV making noises???

but it does it when the car isnt running and only on my P30..
