I still have the same problem before I installed new motor. It starts and idels now but when I start to drive ,motor boggs down. am frustrated. have installed new Alt.,Fuel pump, have 3 air reg, and 3 TPS. Im removing all BS components to clean up my intake manifold. Whare should I run the Vacumme line off the dizzy advance? I Kinked off the return line and was able to keep engine running so I guees the fuel regulater is bad. Have been through all the wires and relays in dash an under hood but still cant drive . Help please. Thxs.

 

That will only complicate things. Do not remove parts until the car is running normal... otherwise you will continue to chase phantom problems forever.

To the TTV on the thermostat housing. Look it up in the FSM (EF & EC)

So replace.
