You forgot to mention the idle speed control solenoid and the crankshaft
position sensor.  Just kidding.

The point I was trying to make is that my experience with TBI vs Multi-port
has been more favorable which I may or may not have erroneously attributed
to fewer parts.

I do know that replacing or rebuilding one injector has got to be cheaper
than four.

> Acually, TBI has a throttle position sensor (TPS), which does the same
thing as the AFM. TPSs and AFMs are both potentiometers, TPS is mechanical
(on the throttle body attached to the trottle valve), AFM is numatic, a flap
that opens with air flow, the more air the more it opens. Both prforme the
same function, to tell the ECU the position of the throttle (how much air is
entering the engine).
