Ask any Honda dealer, and they’ll tell you the repercussions of a faulty ignition coil can be far-reaching, especially if the issue isn’t rectified quickly. Engine failure is the worst-case scenario, so knowing the signs of a failing ignition coil is essential.
Honda Dealer Reveals the Top 5 Signs of a Faulty Ignition Coil
1. Check Engine Light Is On
If your check engine light is on, it could mean the ECU has detected a misfire or faulty coil in one of the cylinders. But you could also look at a defective spark plug or a broken sensor. Either way, taking your car in for a diagnostic scan when the check engine light comes on is best.
A professional-grade scanner can figure out the actual cause of your check engine light. This can help eliminate costly guesswork and can help you avoid unnecessary repairs.
2. Stalling or Hesitating Engine
If your engine stalls out, it can indicate a bad ignition coil or spark plug malfunction. It’s common in older cars with high mileage, but even newer vehicles are susceptible to this problem. This is especially true when dealing with a coil pack system.
Neglecting this problem can lead to further damage, so make sure you get your car checked out as soon as possible.
3. Rough Idling
It’s normal for your car to idle rough when it’s cold outside. But a bad ignition coil can also result in erratic revving, even on a warm day.
If you suspect a bad ignition coil, have your dealership inspect the engine and individual coils. You could look at clogged fuel injectors or a dirty air filter, and the dealer can help solve those issues before installing the new coils.
4. Reduced Power and Acceleration
If your car is losing power, it could be due to a failing ignition coil. This can cause slow acceleration, often accompanied by sputtering or backfiring.
You risk serious mechanical issues if this problem isn’t addressed in time. We are talking about misfiring that could lead to significant engine damage or even an accident.
5. Decreased Fuel Economy
When your car’s fuel economy decreases, it could be a sign that one of the ignition coils is failing. Each misfire uses more fuel than necessary, and the combustion efficiency drops. This issue can lead to poor performance and higher emissions.
The best action is to replace the faulty coils with high-quality OEM components.
Ignition coils are a critical component of your car’s engine, and any sign of malfunction should be taken seriously.
