Alright whenever I start my car now there is a diffrent sounding tone comes from the exhuast till the rpms lower down. Its almost like a humming noise. anyone know what it could be?

 

Is it like pulsating? What performance mods you have?

 

no not really pulsating, it just revs up a tiny bit and then goes down and kinda does it one more time and then its gone. no mods.

 

Does it happen when you turn on the AC or just does when you first start up?

 

Just when it starts up... haha yeah right AC in seattle??? haha

 

Well there was a reflash for jumpy idles for some of the models mine was an 06 and mine needed it do you know if it got it or not?

 

hmmm... I'm pretty sure I didnt get it

 

Well call your dealer it was a recall i believe. Mine got it with out a problem from the dealer.

 

alright thanks I'll call them tomorrow...

 

If that dont fix it let us know i am sure someone will be on to help you out more.

 

it's normal for a car to rev up higher when you start it and then for the rpm's to start to fall after. In your stock tune, the colder the coolant is, the higher your rpms are going to stay.

As for the tone to sound differently I have no clue, colder weather can make cars do odd things.

 

Yeah i know it revs up a little when i start it is normal but it just started this tone.
