Why does my car vibrate when idle or stopped?
Spark plugs, their wiring, and the coils create the voltage to ignite in each cylinder. Spent or old spark plugs become soiled from oil or carbon deposits, greatly reducing the power created from ignition. By replacing your spark plugs every 30,000 to 50,000 miles you’re ensuring a sufficient spark every time.
What does it mean when your car Idles well?
Engines that operate well and idle smoothly indicate that the fuel and air provided to the engine are mixing at the optimal condition. Additionally, a well-functioning engine is able to produce the power needed to operate vital systems such as the cooling system, power steering, air conditioner, and the electrical system.
