this is for an 88 blazer. Is the throttle body completely controled by the tbi.
Not sure exactly what you're asking...
TBI is Throttle Body Injection. The actual injectors (the 2 black plastic barrel-looking things suspended above the throttle bores) are controlled by the computer, along with a couple other things in the throttle body.
If at first you don't succeed, failure may be your style...
