I'm am using a stepper IAC for idle air and want to run my setup by anyone who can comment.
I have tapped into each of my ITB's just in front of the injectors and installed 8MM (slightly over 1/4") take offs. I have piped these all to a foot long "plenum tube" of diameter 1" and my IAC valve regulates air into the tube. I am concerned that this may be allowing one cylinder to pull mixture from another at idle. Am I going the right way with this setup, all comments would be appreciated.
