- Electrical Overload: Too much electricity coursing through the coil can fry its delicate insides. This can happen due to a short circuit or a faulty electrical component.
- Mechanical Damage: Rough roads or careless wrenching can cause the ignition coil’s housing to crack or its connections to loosen, leading to failure.
Signs of a Failing Ignition Coil
A failing ignition coil won’t just silently give up the ghost. It will send you a few distress signals, such as:
- Misfires: Your engine will cough, sputter, and shake like it’s trying to dislodge a stuck burrito.
- Rough Idling: Your car will vibrate like a jackhammer at every stoplight.
- Poor Acceleration: Your car will feel sluggish and unresponsive when you hit the gas.
- No-Start Conditions: If the ignition coil fails completely, your car might refuse to start at all.
Troubleshooting Ignition Coil Failure
If you suspect a failing ignition coil, don’t despair! Here are a few troubleshooting tips to help you narrow down the issue:
- Check for spark: Use a spark tester to see if the ignition coil is generating a spark.
- Inspect the coils: Look for any cracks, burns, or loose connections on the ignition coils.
- Test the coils: Use a multimeter to check the coil’s resistance. If it’s out of spec, it’s time for a replacement.
