Ignition Coil: What It Is and When to See a Mechanic
Your car’s engine needs a spark to run—and that spark starts with the ignition coil. Since this part delivers the high voltage needed to fire the spark plugs, it plays a key role in starting your engine and keeping it running smoothly. Whether you’re driving through Lancaster or heading out for errands, a healthy ignition coil ensures strong performance and better fuel economy.
At Meineke in Lancaster, our ASE-certified mechanics provide ignition system diagnostics, coil replacements, and full tune-ups to help keep your engine in top condition. So, in this post, the experts at Meineke explain what the ignition coil is, how it works, why it’s important, how to maintain it, and when to see a mechanic.
So, What Is an Ignition Coil and How Does It Work?
The ignition coil is an electrical component that transforms your car’s low battery voltage into the high voltage needed to create a spark. Since spark plugs can’t ignite the fuel-air mixture with low voltage alone, the coil boosts the power and sends it to the plugs at exactly the right time.
If the ignition coil fails, then the spark becomes weak or inconsistent—and your engine may misfire, stall, or struggle to start.
So, Why Is the Ignition Coil Important?
Because it’s the source of spark energy, the ignition coil affects how well your engine starts, runs, and performs.
-
Starts your engine smoothly – If the coil works correctly, then the spark plugs fire up the engine without delay.
-
Improves fuel economy – If combustion is strong and complete, then your engine burns less fuel.
-
Prevents misfires and hesitation – If voltage is steady, then your engine avoids stalling or running rough.
-
Reduces harmful emissions – If fuel burns efficiently, then fewer pollutants are released from your exhaust.
So, How Do You Maintain the Ignition Coil?
Although ignition coils don’t require frequent service, good habits help them last longer.
-
Get regular tune-ups – If your spark plugs are worn, then the coil has to work harder to fire them.
-
Address misfires right away – If the engine misfires often, then it can overheat the coil.
-
Avoid driving with old or damaged wires – If wiring is cracked, then power delivery becomes unreliable.
-
Keep the engine bay clean and dry – If water or oil leaks onto the coil, then it could short out or corrode.
So, When Should You See a Mechanic in Lancaster?
Ignition coil problems often show clear symptoms. Visit Meineke in Lancaster if:
-
When your engine misfires or runs rough, the coil may not be delivering enough voltage.
-
If your car is hard to start, weak spark could be the reason.
-
When your check engine light turns on, diagnostic codes may point to a coil fault.
-
If fuel economy drops suddenly, inefficient combustion may be caused by a bad coil.
-
When you notice hesitation during acceleration, spark delivery could be delayed or uneven.
