Ok so my 97 Impreza 2.2l with 4EAT has developed a strange hummmmm fromm inside the intake somewhere. Im running all stock . Its wierd and hard to describe other than a hummmmm..... that can be heard when the car is on. Doesnt go away or get louder or quieter with throttle or anything.
ANy ideas?

My N/A '98 2.2 does this now that I have removed the snorkel thing, but only at idle.
If you have not changed anything, check all intake fittings for tightness.

Yeah its 2.2 NA. It did it just a tad amount for awhile . I removed the intake and was going to instal a short Ram with cone filter setup I bought off ebay. Had it all out and then decided I didnt want to go that route so I put the stock stuff back on and the sound came back and is louder. only hear it at idle.
