Lately I've noticed an odd noise coming from the bottom of the car. It's if you rev the car to 1.5 rpm or so, then the noise rattle in the middle of the car. the sound is kinda of like tickling metal noise. i can't make it wheather it's coming from the bottom of the engine or the middleof the car.?
Anybody experience this?

 

You might have something loose in the exhaust or heat shields. Do you hear the noise at not just 1.5 but 3.0 and 4.5 K RPMs? If so its definately some sort of resonance of metal to metal shields or something.

 

when reving you can definitely not hear anything. It's after the rpm dropped is when the noise starts tickling like metal clinging in the middle of the car. I might take it into the dealer tomorrow. as I still have a warrantee.

 

does the noise go away when you depress the clutch pedal? if so then I'd say you have what I have... bad TO bearing.
