not sure if I can cross this info of to ta zetec from a duratec but when my father had the cel turning on and off in his 95 on the highway it turned out to be a O2 sensor
you can read your owns code by using
this information and with the lsit of
codes here
get the code and let us know what it is and someone should be able to tell you what is going on and what to do to fix it
