Best Answer

Throttle Body Fuel Injection (TBFI). At first, carburetors were replaced with throttle body fuel injection systems (also known as single point or central fuel injectionsystems) that incorporated electrically controlled fuel-injector valves into the throttle body. These were almost a bolt-in replacement for the carburetor, so the automakers didn't have to make any drastic changes to their engine designs. No manufacture of automobiles use this system any longer. Mulit Point is the norm now.

It does not have a carburetor. If it is a 2.5 L 4 cylinder it is TBFI (Throttle Body Fuel Injection). If it is a 3.3 L V6 then it is MPFI (Multi Port Fuel Injection). The TBFI actually looks like a carburator, but all engines are fuel injected.

Your Saturn has no carburetor and therefore has no gas jets. All 1993 Saturn's are Fuel Injected. The S1 is Throttle Body Fuel Injected, (TBFI). On TBFI you will see what looks like a carburetor. In fact the injector is mounted inside the top of the throttle body. Remove the air cleaner and you can see the injectors. The S2 has Sequential Electronic Fuel Injection, (SEFI). Sequential, in which injection is timed to coincide with each cylinder's intake stroke.
