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?

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.
