Two problems related to o2 sensor have been reported for the 1998 Ford Contour. The most recently reported issues are listed below.
Dealer told me electrical system had a short. O2 sensor & computer in car. The car has had to have the O2 sensor replaced 3 times ($1200. 00 charged by to me by dealer each time) and the computer reset. My complaint is that I should not have to pay to have the electrical fixed and the O2 censor replaced again (4 time!!). . . The turn signals work and than do not . . I have been told a short is in the car but Ford will not find for free. . I am tired of fixing this car please please help.
Intermittently when the gas pedal was applied, the vehicle failed to accelerate. This occurred because of an obstruction in the flow of fuel to the engine. The dealership has serviced the vehicle 5 times. They have replaced the fuel pump, the filter and the oxygen sensor. The problem still exist. The dealership refused to service the vehicle anymore because they indicated they have done all they could do to correct this problem. The vehicle leaked oil over the entire engine, the fuel pressure dropped when the vehicle was driven on mountainous areas, a short was found, and wires were found chaffed.
