An active gas warning light when the vehicle has plenty of gasoline.A blinking or intermittently activating check engine light.A significant drop in RPMs while accelerating for no apparent reason.An unexplainably louder-than-usual engine.Some of the most common tell tale signs that a coil may be defective include: Misfiring can cause drag on the crankshaft, and usually results in a very poor performing engine.Ī faulty coil pack will generally have symptoms similar to a faulty spark plug. This causes what's commonly referred to as misfiring. Usually, if a coil pack is bad, there will be a loss of fire or spark in one or more cylinders. When the spark travels to the spark plug, it jumps from the spark plug gap to the ground, causing an explosion of the fuel air mixture inside the cylinder chamber. When the electronic control module (the car computer) sends the signal to the ignition control, the voltage is released from the coil pack through the spark plug cables to the spark plug. Whenever the combustion process is started, the coil pack builds up the energy, as much as 50,000 to 75,000 Volts. When creating a spark at the spark plug, the fire must initiate from a high voltage supply, so as much fuel as possible burns in the cylinder. Coil packs usually create a better spark, which in turn produces better combustion and horsepower in a car's engine.

Generally speaking, coil packs are much more reliable than distributors, because there are no moving parts and because they fire much less often than a distributor. It is an electronically controlled pack of ignition coils regulated by the car's computer and is used to create the spark for each engine cylinder's spark plug. On newer vehicles, a coil pack replaces the distributor.
