Can anyone here tell me what may be causing this sound? It ONLY happens when I start the car up, and when I rev it a little for about 30 seconds, then it's fine till it cools down again. I don't understand. It started 2 days ago and now it's just plain annoying cause I don't know why it's there. It sounds like a cell phone vibrating!

Thanks

 

Anyone? Want to figure it out before school tomorrow!

 

i dont hear anything, check your oil lately?

 

Could be your mufflers just hitting the right tone (resonating), or your pipes rubbing on something.

 

Same thing is happenes to me when I just go in reverse for a few secs at low rpms, I know its coming from the exaust so i gotta look into it more.

 

I think it's the mufflers resonating. It only happens at EXACTLY 1500 RPM, on the dot. It's weird.

 

whats real strange is when your subs and your exhaust hit tones that cancel each other out... if it weren't for the feel of the car still accelerating i would have though that the car was stalling.

 

Any way I can get rid of that annoying sound though?

 

Annnnyone?

 

Honestly dude, id just have a buddy with you to figure out what the noise could be that way he can indicate where the noise it coming from.
