I'm hearing some whining sound whenever I depress the accelerator of my altis. I don't hear this sa iba naming altises. Considering na mine has a higher mileage, maybe its due to worn out parts na din.

Ano kaya kailangan ko palitan?

Note that I still hear it even if my radio is off.

Kung magpapalagay ako ng grounding kit, ano ba pros nito?

TIA
