Cadillac Ignition Service FAQs:
What does an ignition coil do?
The ignition coil is crucial for converting the low current from your car's battery into the energetic charge needed to ignite the fuel and start your engine. When issues arise with your ignition coil, it can lead to various mechanical and performance concerns. Some faulty ignition coil symptoms can include:
- Power Loss: One of the earliest indicators of ignition coil failure is a noticeable loss of power. If your Cadillac feels sluggish and isn't performing as it should, irregular sparks might be disrupting the required combustion process.
- Check Engine Light Is On: A check engine light could mean your vehicle is misfiring or having difficulty starting, sometimes due to a faulty ignition coil.
- Reduced Fuel Economy: If your stops to refuel are becoming more frequent despite driving the same distances, you might have an ignition coil issue. A malfunctioning coil leads to incorrect oxygen sensor readings, which results in excess fuel being used.
- Backfiring: A bad ignition coil could be the reason your vehicle backfires, producing loud bangs, black smoke from the exhaust and a strong gas smell.
- Misfiring Engine: Ignition coil problems can cause engine misfiring during acceleration. Severe misfires might even cause your vehicle to shut down while driving, potentially damaging the catalytic converter and other engine components.
- Hard Starts and Stalling: Your engine needs precise ignition timing, managed by the ignition coil, to start and run smoothly. Malfunctioning coils cause difficulty in starting and can lead to stalling or shutdowns.
- Spluttering and Coughing Sounds: Unusual spluttering and coughing sounds during ignition point to an ignition coil not firing correctly.
- Vibrating Vehicle: Experiencing jerks or vibrations when idling or accelerating? These can be symptoms of a failing ignition coil.
Can a bad coil pack cause a misfire?
