Keep fuel metering crisp and your engine responsive with the Standard Ignition Fuel Injector TJ55. It fits as a direct-fit replacement for the 1990 Chevrolet P30 equipped with the V6-4.3L engine, an application that uses two injectors.
A fuel injector is an electrically operated valve that meters and sprays fuel for the engine on command from the engine's control system. When an injector clogs, sticks, or leaks, it can upset the air-fuel ratio and lead to drivability trouble.
Mechanical job: Opens and closes to deliver a metered, atomized charge of fuel each cycle.
Signs it may need replacing: Rough idle, engine misfire, hesitation, hard starting, or poor fuel economy can point to a failing injector — diagnose the cause before replacing.
Application: The listed 1990 Chevrolet P30 V6-4.3L uses two injectors; order the correct quantity for your engine.
If a faulty injector is the cause of your symptoms, this Standard Ignition unit replaces it. See the Buyer's Guide tab to confirm fitment for your vehicle.
Manufacturer part number TJ55.
