surging

  1. Noobie Bronco Tech Questions. Flame free zone!
    I checked everything i could, vacuum lines are good,i tested the resistance for the IAC and it was at 10 so it was good , replaced tps twice All i can think off is that the truck is thinking its cold and its running rich or something, cause i have a thermostat of 160, im guessing change it...

    So after getting the truck back to spec, now the throttle is surging again, i did remove the rear emissions valve and plugged it with vaccum caps, not sure if its because of that but you never know Any help or suggestions to look into it im all ears! Thanks
