I get a funny noise almost every other time i come to a stop. It sounds like a electric motor hum. it is coming front the engine bay and lasts 3-5 seconds then goes away. it will not happen if not moving. any ideas?/

 

at a stop your not moving,(no fun intended) dose this happen when your braking, or after you have stoped (the noise)

 

i starts a second or two before i am completely stopped then the noise continues for a 3 or 4 more seconds

 

might be your electric fans? Does it do it all the time? Or just when its warm?
I have 2 fans on mine. 1 kicks on as soon as I start my car (my choice) Then the other will kick in I think at 180-220 range (never gets that hot)
Maybe you have a bad fan motor tring to kick on.

 

not the fans - can the egr make noise?

 

do you still have your A/C? Could be your compressor making noise clicking on and off?
I never heard a noise from a EGR valve.
Hummm....I wish I could hear it! LOL!!

 

no a/c - it my be my canister humming - it sounds like a fuel pump hum

 

disconnect the canister, see what happins. I have all of my emissions stuff off, but depends on where you live.
