Without properly working ignition coils, your car won’t start. The ignition coils amplify your Toyota Avalon’s low battery voltage to power the spark plugs. Bad or failing ignition coils can damage the engine and catalytic converter, so should schedule service as soon as possible to avoid more expensive repairs.
Mechanics cannot repair faulty ignition coils. You must replace them with new parts. In some cases, the ignition coil may not be bad but contaminated by an oil leak in the spark plugs. It’s possible an expert can clean your ignition coils, but if you see rust or corrosion, they must be replaced. While a single coil can be replaced, most professionals recommend replacing them together as a preventative measure. The ignition coils are often connected in a single unit called a coil pack.
We know keeping your vehicle in top shape is important to you, and we want to help. Read on for five signs your Toyota Avalon ignition coils are failing.
- Trouble starting the engine
Failing ignition coils will make it take longer for your engine to turn over and start. When the coils don’t function properly, your ignition system must work much harder to create the combustion necessary for your engine to run. When your coils fail completely, your engine won’t produce enough energy for ignition.
- Reduced fuel economy
If a tank of gas isn’t getting you as far as it used to, check your ignition coils and spark plugs. Reduced fuel economy is a common sign of issues with the ignition coils for the Avalon.
- Check engine light comes on
When your Toyota Avalon ignition coils start to fail, they cause your engine to misfire. Usually, it also illuminates the check engine light to tell you there’s a problem. When your dash lights up with a check engine light, M & R Auto will read the codes and help you plan to fix any issues.
- Engine running rough at idle
Rough idling is one clue your Toyota’s ignition coils may be failing. If your engine isn’t running smoothly while at idle, or if you feel vibrations in the cabin, have your mechanic check the ignition coils on your car.
- Loss of power/acceleration
Loss of power and acceleration is a strong indicator you have a problem with your Toyota Avalon’s ignition coils. When they don’t work properly, your engine loses power. If you press the gas pedal and find hesitation to accelerate, have your mechanic check the ignition coils.
Conclusion
Your car needs properly working ignition coils to function. Finding a reliable mechanic to perform service on your vehicle doesn’t have to be a chore. The expert technicians at M & R Auto have the skills and experience, along with industry-best tools, to keep your Toyota Avalon in top condition.
