If your car is running rough, misfiring, or just not starting like it used to, there’s a good chance your ignition coils are on their way out. Ignition coils are a critical part of your car’s ignition system, responsible for providing the high voltage needed to create a spark and ignite the fuel in the engine. When they start to fail, it can lead to all sorts of problems.
In this post, I’ll go over the common symptoms of failing ignition coils, what causes them to fail, and what’s involved in getting them replaced. I’ll also touch on the typical cost for this repair in New Zealand and why My Auto Shop is the best place to get it done.
Symptoms of failing ignition coils
There are several telltale signs that your ignition coils may be failing:
- Engine misfires, especially when accelerating
- Rough idle or stalling, particularly at stops
- Decreased fuel efficiency
- Difficulty starting the engine
- Check engine light is on
- Backfiring or popping sounds from the exhaust
If you’re experiencing one or more of these symptoms, there’s a good chance your ignition coils are to blame. Ignition coils typically fail due to age and wear, but can also be damaged by extreme heat, vibration, or faulty spark plugs.
Ignition coil replacement process
Replacing ignition coils is a straightforward process for a skilled mechanic. It typically involves these steps:
- Locate the ignition coils (usually on top of the engine)
- Disconnect the electrical connectors and remove the coils
- Install the new coils and reconnect the electrical connectors
- Clear any diagnostic trouble codes
- Test drive the vehicle to verify the repair
While it’s a pretty simple procedure, it’s always best to have ignition coils replaced by a professional mechanic. They’ll be able to properly diagnose the issue and ensure the new coils are installed correctly.
Cost of ignition coil replacement in NZ
The cost to replace your ignition coils in New Zealand can vary quite a bit depending on your vehicle make and model and the specific coils needed. On average, you can expect to pay somewhere between $200 to $800+ for the parts and labour.
