try 2 things check all your vacum hoses and the other is get a can of carb cleaner and spray it over your inlet manifold etc

and then if there is an air leak the revs will drop or make it mis-fire slightly
from drawing the carb cleaner in

if you spray in carb cleaner revs will drop and it will missfire wether there is an airleak or not!

because petrol engines dont burn carb cleaner 'cleanly' spraying anything down the intake other than air will cause revs to drop and missfire.

fair but if there is no leak unless you spray it directly onto the air filter it should not matter?
im talking about spraying across the top of the inlet manifold not the filter
