Hey there, it’s your friendly neighbourhood mechanic here to talk about a crucial component of your car’s engine – the spark plugs. These little guys are responsible for igniting the air-fuel mixture in your engine’s cylinders, which powers your vehicle. When they start to fail, you might notice some tell-tale signs that it’s time for a replacement.
Symptoms of failing spark plugs
So, what are the signs that your spark plugs are on their way out? Here are a few to watch out for:
- Rough idle: If your car sounds like it’s having a rough time when you’re stopped at a light, it could be due to misfiring spark plugs.
- Trouble starting: When your spark plugs are worn out, they might not provide enough spark to get your engine going, making it harder to start your car.
- Engine misfiring: If you feel your car jerking or stuttering while driving, it could be because one or more cylinders aren’t firing properly due to bad spark plugs.
- Poor fuel economy: Faulty spark plugs can cause incomplete combustion, meaning you’ll burn through more fuel than usual.
- Lack of acceleration: If your car feels sluggish when you hit the gas, it might be time to check those spark plugs.
What causes spark plugs to fail?
Spark plugs endure a lot of wear and tear over time, exposed to high temperatures and pressures inside your engine. They can become fouled with carbon deposits, which affects their ability to create a strong spark. The gap between the electrodes can also widen over time, weakening the spark.
What’s involved in a spark plug replacement?
Replacing spark plugs is a relatively straightforward process for a skilled mechanic. They’ll remove the old plugs, check the gap on the new ones, and install them in your engine. Depending on your vehicle, they might also replace the spark plug wires at the same time.
How much does it cost to replace spark plugs in NZ?
The cost of a spark plug replacement can vary depending on your vehicle’s make and model, but on average, you can expect to pay around $100 to $200+ for parts and labour. Some high-performance plugs can cost a bit more, but they also tend to last longer.
