Ignition coils sit at the center of every gasoline engine’s spark, yet they usually stay invisible until something goes wrong. When a coil starts to fail, the symptoms can look like fuel problems, ...

Question: I have a 2006 Kia Sedona, and it randomly misfires roughly once for every week of normal driving and once after each carwash. When it happens, I pull over and shut off the car. Then, I turn ...

Just like spark plugs, ignition coils can wear down and become faulty over time. There are many common signs that an ignition coil is getting bad, but one obvious sign is an engine misfire, typically ...

For an engine to create propulsion, it first needs a few core ingredients. The process begins with fuel being pumped through the car's fuel lines and into the combustion chamber. This is where fuel ...

When I attended technical school studying automotive service technology many years ago, among the first things my instructor taught us was the basic principles of how an engine works. These principles ...

The P0351 code means your engine control module (ECM) has detected a malfunction in the ignition coil “A” primary/secondary circuit, which corresponds to cylinder 1 on most engines. When this circuit ...

It’s quite inconvenient to refill your gas tank more than usual. Engine misfires can also be annoying. But before you take your car to the auto shop to see what’s wrong, check your ignition coils.

It’s the kind of moment that makes anyone squint at their receipt like it’s written in a secret code. You pay for new spark plugs, drive away hoping for that smooth, happy idle, and the engine still ...

A misfire indicates there’s something wrong with what keeps a car’s combustion process going. Here’s what it could be, and how to avoid it. Every internal combustion engine, like those in a car, needs ...

A windings road:It all starts with the concepts of inductance and electromagnetism. Inside an ignition coil there are two sets of wire windings (aka coils, that's why it's called a "coil," get it?).

One of the main differences in regular maintenance between a gasoline and a diesel-powered car is replacing the spark plugs. While diesel engines rely on compression to create ignition, and thus ...

Ignition coils play a crucial role in a vehicle’s ignition system. They serve to convert the battery’s low voltage into the high voltage necessary to fire the spark plugs. If there’s any malfunction ...
