    Noobie Bronco Tech Questions. Flame free zone!
    Howdy there! So a few months ago I came across a beat up 96 F250 with a 5.8 that a buddy of mine wanted to scrap.

  8. 91 5.8 FSB ACTS UP WHEN WARM

    1980-'96 Bronco Tech
    (91000 original miles no bull) I am waiting on a scanner to see if it will help me. Not getting any codes. The beast runs fine until it approaches running temperature then starts to deteriorate until a stall occurs. Over winter it ran fine unless I took a long trip but the cooler weather helped...
