While the vacuum tubing is some kind of special hard plastic - crimps fairly easily btw - the connectors clustered at the top of the manifold are simple push on rubber fittings (except for the big EVAP fitting). You can pull them off one at a time and inspect. Try blocking the port temporarily and see if the idle improves to try isolate any offending line.

Did you replace the PCV elbow and valve (front of the engine) when you repaired the collapsed rear hose?
