Installing new spark plugs is the best way to resolve such vibration related issues.
Why does my car engine shake when I drive?
The most prevalent cause of vibration is problems with your wheels or tires. The potential problems include improper wheel and tire balance, uneven tire wear, separated tire tread, out of round tires, damaged wheels and even loose lug nuts.
Is it bad if my engine is shaking?
