Can you drive with a bad ignition coil?

It is possible to drive with a faulty Coil On Plug (COP), but not advisable. Driving with a faulty waste spark ignition system won’t be possible. Driving with a faulty coil pack can damage other components of the engine. You’ll also learn how to diagnose and replace your faulty coil.

How long do ignition coils last?

The ignition coil on your car is supposed to last around 100,000 miles or more. There are a number of factors that can lead to this part become damaged prematurely. Most of the newer cars on the market have a hard plastic cover that is designed to protect the coil from damage.
