i have posted about this before but i cant find the thread so im reposting. i have a 97 contour gl 2.5. the car stalls while driving and wont start for awhile. it turns over but it dont start. before it shuts off the overdrive off light flashes. it has been to ford 5 or 6 times over the past month and a half and ford cant find the problem. they have replaced all 4 02 sensors, the MAP sensor, somehow cleaned the IAC and replaced 2 broken wires they found that went from the MAP sensor to the PCM. i have replaced the spark plugs and wires and the PCM. its an intermittent problem and doesn't seem to happen during any specific driving conditions. Ford says it was running rich and thats why they replaced the oxygen sensors.
