Symptoms of a Bad Coil Pack?

Answer

Some of the symptoms of a bad coil pack include the loss of spark in one or more cylinders, a rough idle, a lack of power in the vehicle, a drop in the revolutions per minute during acceleration, a blinking check engine light or a check engine light that stays on for a period of time, and a gas warning light that comes on even when there is gas in the vehicle. In most cases when the coil pack is bad it will need to be replaced completely.
