A Guide to the Ignition Coil Pack for the 1999-2002 Daewoo Nubira
If your Nubira is running rough, misfiring, or has a check engine light, the ignition coil pack could be the culprit.
- The 1999-2002 Nubira uses a single ignition coil pack, not individual coils.
- Replacement is very easy and a great DIY task you can do in under 30 minutes.
- For best results, always replace spark plugs and wires at the same time as the coil pack.
- Choosing a quality aftermarket brand like Delphi or NGK offers excellent reliability and value.
Is Your Daewoo Nubira Ignition Coil Failing?
When the ignition coil pack in your Nubira starts to fail, it can't produce a strong enough spark. This leads to noticeable engine problems. Because this part is electrical, it can fail suddenly or get progressively worse, especially as the engine warms up.
Common Symptoms of a Bad Coil Pack:
- Engine Misfires: The engine may shake or shudder, especially when idling or accelerating. This can feel like a constant stumble or jerkiness.
- Check Engine Light: A failing coil pack will almost always trigger the Check Engine Light. Common codes include P0300 (Random Misfire) or P0301, P0302, P0303, P0304 for specific cylinders.
- Loss of Power: Your car will feel sluggish and won't accelerate as quickly as it should.
- Rough Idle: The engine will sound and feel rough or unstable when you're stopped.
- Poor Fuel Economy: When your engine isn't burning fuel efficiently due to weak spark, your gas mileage will suffer.
- Hard Starting: The engine may take longer than usual to start, or it might stall after starting.
Important Note on a Related Recall
Daewoo issued a safety recall for the Camshaft Position Sensor (CMP) on some Nubira models. A failing CMP sensor can cause similar issues, including a check engine light and stalling. Before replacing your ignition coil, it's wise to confirm the diagnostic trouble codes to ensure you are replacing the correct part.

For a vehicle like the 1999-2002 Nubira, original factory (OEM) parts can be hard to find. Fortunately, the aftermarket offers a wide range of options. Quality can vary, so it's important to choose a reputable brand.
Brand Quality Tiers
- Premium Aftermarket (OEM-Quality or Better): Brands like Delphi and NGK are well-respected and often supply original parts to car manufacturers. They are known for excellent reliability and performance, making them a top choice for a dependable repair.
- Standard Aftermarket (Reliable Replacements): Standard Motor Products (SMP) is a long-standing brand that offers good quality parts. They are a solid choice that balances cost and quality. Avoid their budget "T-series" line if possible. Brands like Spectra and Walker Products also fall into this reliable replacement category.
- Economy Aftermarket (Budget-Friendly): Brands such as DriveWire, Skyward, and True Tech offer the most affordable options. While they can get your car back on the road, their long-term durability may not match that of premium brands.
Pro Tip: Replace Plugs and Wires at the Same Time
The ignition coil, spark plugs, and spark plug wires all work together. Old spark plugs and wires can put extra strain on a new ignition coil, causing it to fail prematurely. For the best results and to avoid doing the job twice, it is highly recommended to replace the spark plugs and spark plug wires when you install a new coil pack.

Frequently Asked Questions
Is the Daewoo Nubira ignition system coil-on-plug?
No, the 1999-2002 Nubira does not use a coil-on-plug system. It uses a single ignition coil pack that provides spark for all four cylinders via spark plug wires.
How difficult is it to replace the ignition coil pack?
This is a very easy repair that most DIYers can complete in under 30 minutes. The coil pack is located on top of the engine, held in by a few bolts. The process involves disconnecting the battery, unplugging one electrical connector, and swapping the spark plug wires to the new coil.
🎬 Watch this quick walkthrough of the coil pack replacementWhich cylinders are paired on the coil pack?
The Nubira's waste-spark system pairs cylinders that are opposite in the firing order. One internal coil fires cylinders 1 and 4, while the other fires cylinders 2 and 3. The terminals on the coil pack are usually labeled to ensure the spark plug wires are connected correctly.
Can I drive with a bad ignition coil?
It is not recommended. Driving with a constant misfire can allow unburned fuel to enter the exhaust, which can quickly damage the expensive catalytic converter. It's best to get the issue fixed as soon as possible.
