Thanks in advance for any help provided.
My issue is that in troubleshooting a continuous high idle ( on 1992 2wd base P/U w 22RE motor )
in attempting to remove the IACV hose I manage to snap off the "nipple" where the hose from the IACV connects near the thermostat housing.
What I need help in is locating a good digram showing exactly what this hose is connected to, and any advice on how to extract the remaining threads
so that I can screw in a new nipple.

any help and advice appreciated

 

Pictures would be a great help

Are you talking vacuum line or coolant??
