When you Guy's go thru a TBI unit, how far do you go? I have mine all apart, and cleaned, but do I take the injectors apart also? Another question- my injectors are black pins on one with the number GM 71189 on it, and the other has Orange pins, and NO numbers. Does this make a differance? I bought this setup with the motor out of a '95 Suburban that had been impounded by the cops. I found a TBI pod spacer on it, a Hypertech chip in the PCM, and am wondering about the rest of the TBI unit/motor. The cops said they gave them a run for there money 'til caught. Thanks, Al
