I had a check engine light with error code p0420. Had it cleared but it seems that the car rattles for a few seconds when I hit sixty km/hr. Any ideas?
Thanks

420 code is a catalytic converter bad it may have broken something inside causing the noise. Other than that have a mechanic check this locally as we cannot hear it.

Ok. Thanks. It almost feels like a phone vibrating in your hand for 2s. Mechanic said it may be a bad cylinder 2 spark plug. But that's all they could see
