A: There are two sets of windings inside each ignition coil. The primary windings have hundreds of turns of heavy wire, while the secondary side contains thousands of turns of fine wire. Power supplied by the battery flows through the primary windings.

A: If the ignition coil goes bad, the car won't be much fun to drive — it might stall, and will definitely run poorly. Also, the amount of unburned fuel going into the catalytic converter could cause it to fail, adding an expensive repair to your bill. With severe ignition problems, the vehicle should be towed to a repair facility.

A: Some carmakers recommend replacing the ignition coils at scheduled intervals; this schedule should be followed to reduce the likelihood of failure. Some coils will last the lifetime of the vehicle, and other may only last 5,000 miles. Most will make it 60,000 miles or more.

A: For vehicles that use one coil per spark plug: If the engine misfire is only on one cylinder, the components for only that cylinder should be examined. If the coil is suspected, it will be tested and, if faulty, will be replaced. For older cars, with distributors: One coil will fire multiple spark plugs. If all these plugs are failing, the ignition coil will be suspected and tested.

A: Replacing an ignition coil is usually an easy task, and can be done safely by almost anyone as long as precautions are taken against electric shock. In most vehicles, the ignition coil or ignition coils are accessible, and replacing the coil should only take minutes. In some cases, especially for vehicles with individual coil packs installed on each cylinder, removing the rear coil packs may be difficult.
