When to Check the Ignition Coils

A weak ignition coil may contribute to hard starting, rough idle, hesitation, weak acceleration, reduced fuel economy, misfire symptoms, or a check engine light. Similar symptoms can also come from worn spark plugs, wiring problems, fuel delivery faults, intake leaks, sensors, or engine mechanical condition.
