Sorry to bring up a dead thread, I just finished building my hybrid with a vf11 on it and I'm having idling issues. You said that the IACV needs it's own line to the intake, but in your picture it looks like you've got all the lines tee'd into each other. I have all the lines tee'd into each other and kept getting a CEL for the IAC. Should I try and reroute my lines to have the IACV seperate from the PCV and crank vent? I can get a picture of my routing later if that would help.
