Get the Best Priced Toyota Corolla Ignition Coil

For your Toyota Corolla's engine to run smoothly, you need to have all your ignition coils operating at their peak. If even one coil fails, you could find that your engine does not run as well as it should. The problem will not fix itself or get better over time. In fact, it will likely get worse. The best way to ensure that your engine is at top efficiency is to replace any bad ignition coils as soon as they show signs of failure.

What is an Ignition Coil and What Does It Do?

The ignition coil on your Toyota Corolla is designed to send a signal for a given spark plug to ignite. You have as many ignition coils as you do cylinders on your engine on a Corolla, though other vehicles have a single ignition coil. The ignition coils act to step up voltage to the thousands of volts each spark plug requires to create a spark to ignite the fuel in the combustion chamber. Without working ignition coils, your spark plugs will lose their spark, even if they're new. Luckily, whether you drive a 1999 or a 2009 Toyota Corolla, ignition coil problems will show distinct symptoms.

What are the Symptoms of a Bad Ignition Coil?

Toyota Corolla ignition coil problems appear in several ways. You may find that the engine does not start. Misfiring is also a sign of a bad ignition coil because the bad coil keeps its corresponding spark plug from working correctly. If you get a check engine light and pull the trouble code, it will identify exactly which ignition coil is bad. It's important to replace the coil because continuing to drive with a bad ignition coil could cause further damage to the spark plugs, wires, and other components of the ignition system.

What Can Cause an Ignition Coil to Go Bad?

Though ignition coils should last for a long time, sometimes they can go bad. An unaddressed oil leak is a prime cause of ignition coils failing. The hot oil has corrosive properties and can seriously damage an ignition coil's ability to send electricity to the spark plug. Over time, just the heat of operation can cause the ignition coil to wear out. If you drive a high-mileage Corolla, it's possible that one of your ignition coils could go bad just from age. Be vigilant for signs of a bad coil if you have a chronic oil leak or an older vehicle.

How Much is the Ignition Coil Replacement Cost for a Toyota Corolla?

The cost to replace a single ignition coil can be high. For a 1998 Toyota Corolla ignition coil replacement, many mechanics charge between $170 and $216 per coil. This number could increase, especially if you have one or more ignition coils that have gone bad or if other damage was done from the faulty coil. To save money and not have to sacrifice your car for the day to a mechanic or Toyota service center, install a new ignition coil yourself. If you can change spark plugs, you can likely also replace your own ignition coils. PartsGeek.com has everything you need for this task at low prices that you won't need a coupon or a sale to get.
