2007 charger sxt-intermittent humming Sign In

my 2007 dodge charger 3.5 sxt has about 86000 miles on it. usually when excelerating but it also does it when the speed is constant ,the humming comes and goes, it's almost like the engine is reving up but the car is riding fine; no speeding up, jerking or anything like that. this morning it did it while the car was in park and idling. any comments would be appreciated.

Well just a guess would be a bearing starting to make noise..

I would see if I could get the noise to happen sitting still to help find it. While driving turn the a/c on & off, turn the wheels, notice if it was a particular gear this happens in, see if brking had any effect, anything to try to localize it.....

Just sitting in park and idleing, I think I would start by looking under the hood and listening while it runs. Walk around it and try to narrow down the locationof the noise. Also check air intake hoses, making sure they are connected tight. This sounds like a tough one to find-from here. Good luck.
