Humming coming from air intake
There is a humming coming from the engine when I stop the RV or when the RV is in idle. This morning i was able to narrow it down to the air intake. When I give the engine just a little gas it goes away. When I am driving it is not there. Just when I stop. I took the air filter off thinking it might be clogged but when I took the air filter off the sound got louder. I have a majestic RV on the e350 chassis with the triton v8 5.4 liter engine. Anyone have any ideas what it might be or how to repair it?
