2008 MR, stock.

when the temp gets hot, i get this weird clicking vibration in first gear under the gas/brake pedals. slowly accelerating/decelerating does this, and i think turning the steering wheel accentuates it. once i get up to driving speed, it disappears.

i've had it for 2 summers now. any ideas? it's not loud enough to capture on camera, but i can feel it pretty well.

sometimes these vibrations only occurs at just the right temperature and RPM.

 

wouldn't that be more of a tinny popping sound? like the popping sounds you hear from the undercarriage after parking the car from a spirited drive?

this is sounds/feels like something's rubbing one something else.
