Air Box NOISE...wierd 900 1993

My 93-940 air box is making a loud rythmic hum. What is in there that could make that kind of noise? It is not coming from the throttle body hose or the engine recycle hose, but directly from inside the engine side port and from the top where the intake hose attaches of the air box.

What is doing this?

Don

It's amazing what can be found inside those things. My brother-in-law's was full of dry dog food that the pack rats had stored away there. My mother-in-law's had a dead litter of baby rabbits.

As David said, you probably want to pull the air filter out. It could have leaves or foam that is getting sucked against the element and creating the humming (vibrating) noise.

Have you looked inside the air box, is the filter seated properly, maybe there is a mouse in there. Your previous post does say if you have ever looked inside it.????
