    follow that line back and see where the vacuum stops. (could be a solenoid or temp controlled switch or just a blocked port)

You may have a carbon buildup problem in the egr system, i would check this and the hoses for leaks first

My 1984 Nissan/Datsun pickup has been running rough since I bought it. Me and my dad switched out the Carb on it, and it ran better, but still not great. It stalls out at idle a lot, as well as sounds like...


If you replaced the carb with a used one you might still have a carb problem. Have you done the basics, ie ignition timing, point gap, etc? Does sound carb related though.
