Distributor
Routes high-tension spark to each cylinder in firing order on older engines, and carries the pickup that supplies engine speed. Mechanical wear matters here in a way it does not for solid-state sensors: a worn shaft lets the pickup gap wander as the engine runs.
Also known as: dizzy, distributor cap, distributor assembly, rotor arm

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 you measured, not only what you replaced.
- What actually fixed it — or that nothing did, which is worth knowing too.
