You must also clean the orfices inside the engine. Clamps aren't an issuse unles the hoses come off.

Suggested Repair

Clean the PCV orifices (holes) inside the intake manifold, not only the valve. Hose clamps are not a problem unless the hoses come off.

Conversation Summary

A 1993 Honda idles roughly but does not stall. A mechanic suggested the PCV valve; the owner cleaned it, confirmed air passes through, and found it is not stuck, and also noted the connecting hose has no clamps. The expert said the orifices inside the engine must also be cleaned and explained those are the holes in the intake manifold. Clamps are not an issue unless the hoses come off.
