Strange Humming Noise?
I noticed last week that when the car is at idle,i get a strange humming noise from underneath or the engine bay. also noticed if i accelerate it stops. Another thing is my ac has to be charged but if I turn it on it goes away sometimes? Can the switch be bad? Anyone come across the same issue?

Sounds like you may just have something loose with the exhaust , a heat shield or just exhaust pipe hitting under the car making it sound like it was coming from the engine compartment. Especially if you changed the exhaust you have a bigger chance of noise. Best thing to do is get a buddy and have him/her either sit the car with it in gear or running and you look around the car and pinpoint were the noise is coming from.
