how to replace fuel injector throttle body in a 1988 nissan pathfinder 3.
1 injector
If your vehicle has a throttle body injection system ( TBI ) the injector(s) is in the throttle body wich looks similar to a carburator. If your vehicle has a multi port fuel injection system there is one injector for each cylinder located on the head or in the intake manifold generally connected by a fuel rail.
Pouring the injector cleaner down the throttle body won't clean the injectors. You need to add the injector cleaner to the fuel tank for it to help you. Read the instructions on the container of injector cleaner.
Gas pouring out of the throttle body would probably be caused by a leaking injector seal.
In the throttle body, no but each fuel injector (there is two of them) has a filter.
The only sensors that I am aware of on the throttle body is the throttle position sensor.
If your referring to a fuel injector. Follow the air intake tube in to the engine and it will run right into the throttle body on the norm.
The 1996 Chevrolet Silverado no longer came with throttle body fuel injection. It probably has the central sequential fuel injection system (CSFI) where each cylinder has its own fuel injector.
Check the injector (inside the throttle body)
Nope
The air intake filter assembly would be connected to the throttle body.
