Hi there - your misfire symptoms suggest an air leak in the engine intake system. This could be an air inlet hose as you suggest, a loose or leaking gasket in the manifold or vacuum hoses, or cracked component which is leaking air into the engine. I recommend an engine misfire inspection performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
