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 ...

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?).

For the average beginner in the fine art of auto mechanics, and some old-timers as well, installing and wiring a stock eight-cylinder ignition distributor can sometimes be quite a chore, and when he ...

Sudden misfires feel like the engine just lost its rhythm, yet the real drama often starts inside a failing coil pack. When ignition coils break down under heat, vibration, or age, they can turn a ...

Heat initiates the internal combustion process. Diesel engines utilize the temperature buildup from extremely high compression (pressure) to ignite the air/fuel mixture, with a little help from glow ...

Automotive ignitions systems have seen many transitions over the years. Historically, the designs have matured from a magneto to today’s coil-over-spark plug designs. The progression follows the ...
