Ignition Module
Switches coil primary current, and on distributor systems provides the engine speed signal. Classically heat-sensitive: fine when cold, failing after twenty minutes of running, working again once cooled — a pattern that makes it very hard to catch in a workshop.
Also known as: igniter, ignition control module, icm, ignition amplifier, power stage, ignitor

Information, not instruction
CarGeek is a reference, not a service manual. Its pages are written from public sources and from what other people have found, never from a manufacturer's own service information, so they can be wrong or incomplete for your particular vehicle. Some of what they describe carries real risk: high voltage, fuel under pressure, stored energy, hot and moving parts.
Have anything you intend to act on checked by a trained person against the manufacturer's own procedure for your vehicle. Nothing here replaces that procedure.

What makes one worth reading:
- The car — make, model, year and engine. The same fault behaves differently on each.
- What you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
