Sounds like a vacuum leak
Could be split or loose vac hose, loose inlet manifold or even gasket is gone. Have a really good check use a bit of hose to listen or even use carby/throttlebody cleaner spray it around inlet manifold gasket if revs increase or change even like a miss or a cough you have found problem

If it all checks out ok and no vac leaks start looking at fuel pressure and even ignition timing
