Well for a while now my car has made a humming sound which is pretty loud. It's hasn't been happening very often but here recently it has been. I just got done washing her and she must have done it about 10 times in 45-1 hr. time. Anyone else got this problem or know what the cause is? It's beginning to worry me

 

mine hums all the time when i leave my car alone. doesnt bother me as long as it doesnt affect performance or the car itself.

 

its something in the intake...every honda i've owned has done it.

 

ok i just wasn't sure if it was an issue thanks guys

 

i like my loud hum....it sounds kinda intimidating

 

My CAI is definately a hummer/whisperer. Even before the CAI it hummed, just not as loud.

 

It sounds like the fuel pump. It will prime itself to maintain pressure in the fuel lines.
