How does a coil pack work?

Can I drive my car with a bad coil pack?

While doing so you will, as pointed out by other answers, run the risk of damaging the converter but you also run the risk of fire. If the coil is faulty very bad things can happen. The symptom of a bad coil pack is just a misfire.

Can you replace just one coil pack?

Ignition coil failure can be caused by faulty spark plugs or wires. The mechanic will inspect and may recommend replacement of those components. In a coil-on-plug ignition system, if only one coil fails, you need only replace the faulty coil. Remaining functioning coils can be left in place.

Do ignition coils go bad at the same time?

Ignition coils are common to fail in many cars. Symptoms of a bad ignition coil include engine shaking, sputtering and lack of power (misfiring).
