1989 FORD ESCORT: 4cyl 9 1.9LTBI SOHC vs. 4cyl I 1.9L MFI SOHC HO engines?

What is and how to tell difference between them?


Now Autozone tells me there is a CFI classification, also! Whats' up with this?

    The TBI will have one fuel line connected to the throttle body. The MFI(actually MultiPortInjection)will have a fuel line hooked up to a runner with an injector at each cylinder.

    One would be throttle body, the other is multi port fuel injection
