1993 Oldsmobile Ciera Carb Or EFI

Actually, fuel injection is more efficient. It injects fuel into the engine. A carb relied on engine vacuum to draw fuel into the engine. Also, a carb is not as efficient as injection. Cold starts relied on a choke which prevented air from entering the engine which would draw more fuel. As a result, more fuel was consumed. Therefore, it was harder on the environment. Overall, fuel injection is more efficient, more enviromentaly friendly, and will produce more power from the engine.
