Dear spook, I replaced the O2 sensor on my 94 944NA with Bosch system last fall. I remember buying a sensor for Ford, cutting off the connector, and splice the wires (two for heating, and one for signal). The cost of the Ford sensor is between $30 and $40. I think my car has a 230FD engine. The O2 sensor worked fine on the car. I even wrote a post after doing that with all the detailed information (part number, etc.) for others' reference in future. However, I could not find the post by using the search option. The post was written betwen last October and November, and I used the screen name 'masupra'. If you know there's a way to locate the post by a specific author, please let me know. I will try to find it out.
