Update, Well I've been messing with this issue all week and I've learned that the car runs lean at idle almost all the time with both ECU's so I'm fairly certain it isn't them. (one wolfe, one enthalpy) I took apart the IACV and tested it today. had 9.5 ohm on AAC and 20 ohms on the other valve. Both actuate propery when powered. I have power to them and they are now clean as can be. No change though. o2 has 12 volt power, ground, and signal stayed between 49 and 53 mv with the AFR just over 18. Going to unplug MAF tomorrow and measure the voltage again. It didn't change much when I revved it a idle though.(its also brand new) one the firewall side of fusebox I only have the middle plug installed. Is that the only one required? there's a grey socket and brown socket also. wondering because another Zilvian had the same issue and his happened to be a wrongly pinned brown connector for
o2 and IACV. Any ideas? Anyone?
