When I was driving I noticed a faint "chika chika chika" sound that sounded like it was coming from my wheels. As I sped up and slowed down the sound sped up and slowed down as well. What could this be? I hope it's nothing serious. Also, when I'm driving and shifting gears as I press down on the gas the car kind of shakes and sputters and the only way to stop it is to give more gas. Then it gets really loud and speeds up a little and eventually gets smoother. I think it might be a hole in the exhaust but I'm not sure... help

 

if it was a hole in the exhaust the noise would be a really annoying buzz sound when you would floor it. its possible its your cv joints if you say its coming from your wheels. why dont you put the car on jack stands and get under the car and have a friend drive the car on stands.

 

Whenever I floor it or rev my engine there's a really deep humming sound. It sounds like my car has a really nice exhaust or something but it's just stock and this problem appeared out of nowhere.

 

Is this Mazda's trademark or something.... lol.... when my sister had the car every time she would make a hard left turn it would make this horrible clicking noise. So we took it in.. had it checked and fixed... now the car is mine and it's been less than a year and the car is already doing the same exact thing.... to me this is really embarassing.... and makes my car seem like a peice of $hit to everybody in it that knows nothing about it?.. i'm hoping it's the cv-joint and nothing else...

 

well if yoou have a deep humming that probly is a leek.
