Standard Motor Products
Standard Ignition TJ25 fuel injector for the 1989-1993 Chevrolet Caprice V8 5.7L and other vehicles delivers fuel to the engine when the computer commands it. It is a throttle body injection (TBI) unit.
Hard starting, a rough idle or hesitation can mean this injector is worn, though a weak fuel pressure regulator or a faulty throttle position sensor can be behind them as well. Find out which part is at fault before ordering. These vehicles take two injectors; this listing is one.
It fits the 1989-1993 Chevrolet Caprice V8 5.7L and the 1991-1993 Chevrolet Commercial Chassis V8 5.7L.
