I have a 1986 bronco 2 with a 2.9 the bronco high idles constantly no matter if I unplug the IACV or not. Also it runs so rich when you snap the throttle it bogs and black smoke comes out the tell pipe any form of direction would help greatly

I have experienced some TBI's (not exactly yours), with fuel leakage in o-ring injector.
