Vehicle
Pontiac G8
A Holden Commodore shipped from Australia and rebadged, which is why almost nothing about it matches the rest of the Pontiac range: rear-wheel drive, a Zeta platform shared with the Camaro, and right-hand-drive-market wiring conventions converted rather than designed. Australian Commodore information is the deepest source on it by a wide margin. Sold for two years before the brand closed, so the population is small and the parts situation is its own diagnostic constraint.

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.
