Your Mitsubishi’s ignition coil plays a crucial role in starting your car’s engine. It converts the battery’s low current into enough power to ignite the fuel. A faulty ignition coil will cause various vehicle problems, from a loss of power and high fuel consumption to rough idling and stalling issues. Your Mitsubishi dealer has provided a list of symptoms below to help you identify ignition coil problems and get the necessary repairs before causing extensive damage.
Unresponsiveness
If you experience a decrease in power when you press the accelerator, a malfunctioning ignition coil could be the cause. When the fuel-air mixture inside the engine doesn’t ignite effectively, it can cause your vehicle to respond sluggishly.
Vibrations and Rough Idling
A failing ignition coil can disrupt the smooth operation of your vehicle. When the coil doesn’t work correctly, your car may experience vibrations, rough idling, and sudden jerks when you accelerate to increase your speed.
Misfires
When one of the cylinders isn’t firing properly or doesn’t fire, it can lead to misfiring. The result is smoke from your tailpipe, a gas smell, and loud banging noises from the unused gas exploding in the combustion cylinders. Misfiring can significantly damage engine components and the catalytic converter, resulting in high repair costs.
Unfamiliar Sounds
In addition to loud banging noises, you may also hear coughing or spluttering noises when you start the engine. These sounds are generally due to a cylinder not firing during the ignition process.
Stalling
If your car’s ignition coil starts to fail, it may cause the spark plugs to spark irregularly. As a result, you may experience stalling issues when idling, or your vehicle may even shut down abruptly without any warning.
Hard Starts
When you turn the key in the ignition, a clicking sound may indicate a problem with the ignition coil, making it hard to start your vehicle. Your vehicle’s ignition system requires a spark to start the engine. If the ignition coil is faulty, it may not provide the proper voltage to the spark plugs, resulting in hard starts.
High Fuel Consumption
If your car’s fuel consumption has increased lately, the ignition coil may be the culprit. When the spark plugs do not receive enough power from the car battery, your car will burn more fuel to compensate for it. The result is more frequent trips to the gas station.
Illuminated Check Engine Light
Problems with the ignition coil will cause hard starts and misfiring, triggering the check engine light on your dashboard. When the light is on, schedule an appointment as soon as possible for a diagnostic test and the necessary repairs to prevent severe damage.
