Hello everybody.

one of these days waiting for the semafor the car started making a rattling noise like metal.i dont know what it is but happend 5 days after changing spark plugs.i feel like losing power when going from 1 gear to 2 gear..and when going from 2 gear to 3 gear the clutch is engaged to change but the throttle goes up..

Sounds like the Dual Mass Flywheel (DMF) of your transmission. Open up the hood and see if the sound is coming from the right-side, above where the transmission is. Sound should be louder right below the transmission.

If it's a pulley, then it's a much cheaper fix. Good luck and let us know what caused the sound in the end.
