Hey this may bee too late but i have 95 mystique with 2.0 zeetech. my car did somthing very similar to that and of all stupid dumb ass ford things it could have been it was spark plugs. See the zeetech and i imagine the duratech also runs on a plug with special restinace so if you have perfomance wires and plugs that are not licensed by ford that could be the problem. I fixed with distrubiutor form Accel may be thats propblem. all i know is these cars can impossible to figure out when somthing like that happens. Peace
