Have you ran a code check, could be a MAP sensor, an ACT sensor or even a bad ground.

Did you check the ISC too make sure it is rotating in and out, I have seen these just lockup. Backfire through the TBI is usually a timing problem, did you unplug the spout connector before you set the base timing?
