Engine runs rough. Especially when cold. Checked vacuum, no vacuum at manifold. Guessing either gaskets or since it's plastic, maybe cracked. A lot of work involved so I want to be sure. Any ideas?

I would suspect a vaccum leak since there is absolutely none at the manifold?

Try attaching it to another hose and see.

Take a can of carb cleaner and start the vehicle and spray around the manifolds gasket and throttle bod and manifold itself, idle should increase if theres a leak.
