Keep fuel delivery crisp and metered with the Standard Ignition Fuel Injector TJ47. It drops in as a direct-fit replacement for the 1990-1992 Chevrolet Lumina, restoring the precise spray the engine needs for smooth running.
A fuel injector is the electrically controlled valve that meters and atomizes fuel into the intake, opening and closing on command from the engine's computer to deliver the right amount of fuel for the operating conditions.
- Precise metering: opens and closes to deliver a controlled, atomized fuel charge for consistent combustion.
- Direct-fit replacement: a direct-fit replacement for the listed application.
- Signs it may need replacing: rough idle, hesitation, misfire, hard starting, or poor fuel economy can point to a worn or leaking injector — diagnose the cause first, and if a failed injector is confirmed, this replaces it.
Because these symptoms can have other causes, verify the injector is at fault before replacing. Injectors are often serviced as a matched group, so consider the condition of the others when servicing.
Interchange: Manufacturer part number TJ47.
