the vac diagram give here is correct. I own a 305cu chevrolet.4barrel carb.
the ported vacuum line goes to the electrical solenoid. the other port goes to the EGR port . the PCM turns on the vac to the EGR when its at the proper engine operation.
if the vac lines are not properlly connected it will run like crap.
also make sure the cannister control vac valve is not broken leaking or disconnected.
