just on the injectors
Yes, the 94 had throttle body injection.
Which part is not shared by both throttle body injection and a carburetor ?
That would be throttle body injection (TBI).
1 injector
Yes, throttle body injection.
tbi is Chevy's abbreviation for Throttle Body Injection. In this type of fuel injection system fuel is squirted into the throttle body above the manifold.
No
Yes it does. It has throttle body injection. Jim
TBI or Throttle Body Injection
On a 1987 Chevy Celebrity with a 2.8L multi-port fuel injection engine, the throttle position sensor (TPS) is located on the throttle body, which is mounted on the intake manifold. It is typically positioned on the side of the throttle body and can be identified by its electrical connector and a small lever that connects to the throttle plate. To access it, you may need to remove any air intake components or ducting that obstructs the view.
It's typically a "throttle body" injection vehicle. The box that sits on top of the intake manifold is called the throttle body, and the injectors are in there.
Throttle body injection has one injector located in the throttle body that supplies fuel to the intake manifold. This fuel flows to all cylinders just like it does on a vehicle with a carburetor. Port injection uses tubes with poppet valves from a central injector to spray fuel at each intake port rather than the central throttle body.
