    89 ef hatch, b18 swap obd0 mpfi wiring. iacv deleted, the idle once warmed up is about 1400. Anyway to bring it back down, adjust tps or set screw in the center top of throttle body? car also runs a little rich, just need to pass emissions by 31st.

    U either have a big vacuum leak or you need to hook the iacv back up.

    since the original thread is now about 9 months old, he has probably already solved the problem

    Fixed Idle

    We actually found a bad vacuum plug under the intake about two days ago, it runs great now. It has very low idle when cold but as it warms up it idles higher. Thinking about swapping to h22 next but looking at some of the write ups looks like a lot of fabrication to get it to fit.
