I'm having a problem with the HEGO sensor, curcuit or as I suspect, the PCM on my '93 4.0 AWD Aerostar. This is really a problem for an experienced Ford engine controller tech. I have a detailed discription of what its doing and what I've done in the Aerostar section. Any help is greatly appreciated. Thanks!

In laymans terms, I think you are having a problem with your O2 sensor, is that right? Not that high tech. Did you know you can test them to see if they are working correctly?
