fixes? anyone else have this problem, heard it the loudest in the beginning

[rhysmcinerney]

i heard it briefly but a better video is needed.

[Burrcold]

I couldn't hear anything and that video was terrible.

[lavisxice]

My FR-S rattles on acceleration from time to time, where does it sound like it is coming from?

[Yruyur]

Need better video and where you think it's coming from. There are a tin of threads in fixes and complaints for the shield underneath that needs washers(mine always rattled at 4200rpm under load), shifter rattle, door panel rattle with music, under the dash area and the sound tube being mounted with a soft rubber that allows the resonator to hit the top of the engine.

Sent from my flux capacitor using Taptalk

the rattle usually occurs at low rpm when i add little throttle, and the sound always comes from under the car.

The problem is that you are shifting too early, the engine was designed to shift up at a higher rpm(3k), from the video you were already changing gears when you just got to 2k rpm.

You should be downshifting if your RPM is around 1,500 and try to keep it above 1,800 if you want to gradually accelerate.

You can cruise at 1,500 rpm but you must downshift if you want to accelerate. If you are at 1,500 rpm and start to accelerate, you are damaging your powertrain from those vibrations!

As far as vibration when starting from idle, same thing. You let go of the clutch too early AND your rpm is not high enough. I dont know the starting point from idle because I never look at my gauge but you should be starting around 1,500 rpm and keep the clutch in until you feel the gear butters up(8mph +/-).

It sounds a bit more complicated than it really is, but all it takes is for a couple weeks of practice and getting use to it. Goodluck

Yeah I also currently drive an older 1997 Impreza 5spd and I know exactly what you mean.
