Common signs of ignition coil failure include difficulty or inability to start the engine, unstable idle, poor acceleration, and so on. It is important to promptly check for ignition coil failure because if left unresolved, it can lead to more serious engine issues and even compromise driving safety.

Ignition coils typically have a long life of operation — over 100,000 miles. However, they can malfunction eventually, causing that dreaded misfire.
