Vehicle
Mercury Grand Marquis
The full-size body-on-frame saloon, and a Ford Crown Victoria in everything but the badge — the Panther platform ran essentially unchanged for two decades, which makes it one of the best-understood cars in North America and one of the easiest to find parts knowledge for. The 4.6 modular V8's intake manifold cracked at the coolant crossover on early cars, and the ignition coil-on-plug packs are the usual source of a misfire code. Fleet and taxi mileages mean most survivors are far past the point where wear items are the first suspect.

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.
