I agree. I just have the iacv hose capped off and the fitting deleted on the ic piping. So far it wont stay running at all in the morning when its cold. Its a pita, i have to sit in the car until the car warms up slightly. Which is usally when the needle reaches the very bottom of the c on the stock water temp gauge. It also like to run very rich when its cold like 10:1 air fuel, but that may just be in the jwt ecu. Also the idle like to jump up and down a small amount. But i still have to set my timing and some of these problems may go away.
