after some tedious back and forth with mechanics, i had come to conclusion that my injectors needed replacing. during the weekend i had purchased new injectors and decided to replace them, after replacing them putting everything back as it was, replaced some old vacuum lines and tightened everything back to spec, i go to turn the car on and it cranks, starts but then runs rough for a few seconds then just shuts itself off. i was left baffled and confused on whats going on, seems to me the injectors are doing fine and trying to keep the car running however something else is refusing to let the car run. Ive got a 40 anniversary 97 80 series 1fzfe. any help would be much apprciated thanks guys!
