Ignition Coil Repair

Considering an ignition coil replacement is essential for maintaining your vehicle’s
performance and reliability. Here are the situations when you should consider replacing your ignition coil:

Engine Misfires:

If your engine misfires, especially under load or acceleration, it
could be due to a faulty ignition coil. Misfires can lead to a rough running engine and decreased performance.

Check Engine Light is On:

If the check engine light is illuminated and a diagnostic test reveals an ignition coil-related code (e.g., P0351-P0358), it’s a
sign that the ignition coil might need replacement.

Rough Idling:

If your engine idles roughly or inconsistently, a failing ignition coil could be the cause. This happens because the coil isn’t providing enough spark to ignite the fuel-air mixture efficiently.

Difficulty Starting the Vehicle:

If you have trouble starting your vehicle, especially in cold weather, it could be due to a weakened ignition coil that isn’t
providing a strong enough spark.

Decreased Fuel Efficiency:

A faulty ignition coil can cause your engine to work harder, leading to increased fuel consumption. If you notice a sudden drop in fuel efficiency, it might be time to check the ignition coil.

Loss of Power:

If your vehicle experiences a noticeable loss of power, especially during acceleration or while driving uphill, it could indicate an issue with the
ignition coil.

Backfiring:

A failing ignition coil can cause incomplete combustion, leading to backfiring. This is when unburned fuel is expelled through the exhaust system
and ignites, causing a loud popping noise.

Increased Emissions:

If you fail an emissions test, a malfunctioning ignition coil could be to blame, as it can cause incomplete combustion and higher emissions.

Visible Damage:

If you inspect the ignition coil and notice visible signs of damage, such as cracks, burns, or corrosion, it’s a clear indication that it needs to be replaced.

High Mileage:

Ignition coils can wear out over time, especially if your vehicle has high mileage. Regular inspections and preventive maintenance can help identify
when it’s time for a replacement.

Error Codes from OBD-II Scanner:

If an OBD-II scanner reveals specific error
codes related to ignition coil problems (like P035X series codes, where X indicates the specific cylinder), it’s a strong indication that the ignition coil needs
attention.
