Ported Vacuum Switch
I replaced the 4 port vacuum switch with the black standard motor products (pvs26) one many people have got off of rockauto. I have removed all of the emissions stuff except for the EVAP system PCV, and the vac advance on the dizzy (had to adjust vac advance waaaay down). Does anyone know when the ports are supposed to be open/closed on the switch? None seem to be open when cold. I assume the bottom pair is an in/out pair, and the top pair is an in/out pair. I plan to use the switch for other functions, but need to know the temp range, and I can't find that info anywhere.
