Your Ford's ignition coil is a crucial engine component providing the spark to ignite the fuel/air mixture that powers your ride. If this coil fails, it can cause a range of issues that can significantly impact your vehicle's performance. Here are five common symptoms of a faulty ignition coil, so you can catch the issue at your Ford dealer before it becomes a more significant problem.
If You Recognize these 5 Signs Contact Your Ford Dealer
Hard Starts
A bad or failing ignition coil can cause hard starts in any make of vehicle: not just your Ford. A bad or failing coil results in a weakened spark that cannot fully combust the fuel in your engine's cylinders. This may cause the engine to struggle to turn over, misfire, or stall. If hard starts are your problem, especially if they occur with some of the other symptoms listed here, schedule a service appointment as soon as possible.
Rough Running
Is your Ford's engine running rough? It might mean your ignition coil is wonky. When spark plugs don't get enough voltage to ignite the fuel/air mix, a rough idle is likely. This can cause more than just a rough engine: it can lead to reduced fuel efficiency, higher emissions, and excessive vibrations or strange noises. Don't wait for a rough-running engine to rattle your fillings. Have a professional check out the ignition system ASAP.
Misfires and Backfires
Misfires or backfires are yet another sign of a bad ignition coil. Think of misfires as an internal combustion hiccup when your engine isn't getting enough juice from the coil to fire the spark plugs for complete fuel combustion. A full-fledged burp is a backfire that can produce loud popping or banging sounds from the exhaust system. Both mean it's time to have a qualified mechanic check out your car's ignition system, including the all-important coil.
Poor Mileage
Is your Ford suffering from a dip in fuel efficiency? When an ignition coil functions improperly, incomplete combustion may occur, resulting in wasted fuel and lower fuel efficiency. Additionally, the engine may run rich, meaning it uses more fuel than necessary. You'll need to fill up more often, busting your budget regarding gas costs. To avoid pain at the pump, have a qualified mechanic inspect your ignition coil if your gas mileage drops.
Check Engine Light
The bane of every auto owner's existence, the "Check Engine" light can light up for many reasons. While a bad ignition coil is at or near the top of every mechanic's list of possible culprits, it usually requires some technology to diagnose the exact issue. If you are staring at the "Check Engine" light, have a certified Ford technician identify the problem using an OBD-II scanner to retrieve stored trouble codes in the vehicle's computer system.
 There you have it: five telltale signs, from hard starts to poor gas mileage, that could mean an issue with your car's ignition coil.
