2016 Chevrolet Spark Ignition Coil Pack: Misfires, Stalling, and Easy Fixes

Symptoms of a Failing 2016 Spark Ignition Coil

When the ignition coil pack on your 2016 Spark begins to fail, the signs are usually hard to miss. Because it's a single unit responsible for all four cylinders, a failure can significantly impact engine performance. Here are the most common symptoms:

• Check Engine Light (CEL): This is often the first sign. If the light is steady, you should get it checked soon. If it's flashing, it indicates a severe misfire that could damage your catalytic converter, and you should stop driving as soon as it's safe to do so. Common codes include P0300 (Random/Multiple Cylinder Misfire) and P0301-P0304 (Misfire in a specific cylinder).

• Engine Misfires and Rough Idle: You'll feel the engine shaking, sputtering, or running unevenly, especially when stopped or at low speeds. This happens because one or more cylinders aren't firing correctly.
• Hesitation and Lack of Power: Your Spark may feel sluggish when you accelerate. The engine struggles to produce power when it's not firing on all cylinders.
• Poor Fuel Economy: When the engine isn't running efficiently due to misfires, it has to burn more fuel to produce the same amount of power, leading to a noticeable drop in your MPG.
• Difficulty Starting or Stalling: A weak or dead coil pack can make it hard for the engine to start, especially when cold. In some cases, the engine may stall unexpectedly while idling at a stoplight.

Buying a Used 2016 Spark Ignition Coil: What to Check

For a part like this, a high-quality used OEM coil is often a better and more reliable choice than a cheap, new aftermarket part. Forum users and mechanics frequently report that low-cost aftermarket coils for the Spark can fail quickly. A genuine GM part from a low-mileage donor vehicle provides proven durability at a fraction of the new price.

Physical Inspection Checklist:

• Check for Cracks: Carefully inspect the black plastic housing. Heat and vibration can cause hairline cracks, which allow moisture to enter and short out the internal electronics. Reject any coil with visible cracks.
• Inspect the Electrical Connector: Look at the 4-pin connector. Ensure the plastic isn't broken and the pins inside are straight, clean, and free of corrosion.
• Examine the Boots: The four rubber boots that seal against the spark plugs should be soft, pliable, and free of tears or cracks. Brittle or oily boots suggest the part is old or was exposed to an engine leak.
• Look for Corrosion: Check the metal springs inside the boots. They should be clean and shiny. Heavy corrosion on the springs is a major red flag and a common failure point.

Compatibility Verification:

This ignition coil pack fits 2016-2022 Chevrolet Spark models equipped with the 1.4L LV7 engine. It will NOT fit the older 2013-2015 Spark models with the 1.2L engine. Always verify the part came from a 2016 or newer Spark before purchasing.

Known Issues, Recalls, and Service Bulletins

There are no specific recalls or widespread Technical Service Bulletins (TSBs) from GM for premature ignition coil failure on the 2016 Spark. Failures are generally considered a result of normal wear and tear over time and mileage. The most common causes of failure are heat cycles, engine vibration, and stress from worn-out spark plugs. There was a recall for the 2016 Spark related to the airbag system and another for the radio software, but neither affects the ignition system.

Step-by-Step Replacement Guide (DIY)

Replacing the ignition coil on a 2016 Spark is one of the easiest maintenance jobs you can do.

• Difficulty: 1 out of 5
• Time: 15-20 minutes
• Tools Needed: Ratchet, T30 Torx socket.

1. Locate the Coil Pack: Open the hood. The coil pack is the black rectangular component sitting directly on top of the engine, with a plastic "ECOTEC" cover on it.
2. Remove the Cover: The ECOTEC cover simply pops off with a gentle pull.
3. Disconnect the Electrical Connector: Press the tab on the electrical connector and pull it straight off the coil pack. Be careful, as the plastic clip can be brittle.
4. Remove Mounting Bolts: Use a T30 Torx socket to remove the two bolts holding the coil pack to the engine valve cover.
5. Remove the Old Coil Pack: Gently but firmly pull the entire coil pack assembly straight up. It may take a little wiggling to release the boots from the spark plugs.
6. Install the New Coil Pack: Apply a small amount of dielectric grease to the inside of the new coil's boots. This helps with electrical contact and makes future removal easier. Carefully align the boots with the spark plug holes and press the new coil pack down firmly into place.
7. Reassemble: Re-install the two T30 bolts and tighten them until snug (torque spec is about 7 ft-lbs or 89 lb-in). Reconnect the electrical connector until it clicks. Pop the ECOTEC cover back on.
