Hello, my name is ***** ***** I will assist you today. You have a huge vacuum leak somewhere. I have seen issues where the intake manifold does not line up with the dowel pins on the cylinder head and then does not sit flush. That in turn causes a big vacuum leak. Check that very closely. Use a mirror if you have to. If you are sure that the intake is not the problem, then look for another vacuum leak. I hope this helps and let me know what you find.
