Hello, I have searched the threads before making a new one but I still have some questions, I have a 1996 ford explorer and have codes 172 & 174, O2 sensors left and right BUT does that include the O2 sensors at before and after the CAT? or due they have their own code? I have replaced the EGR, EGR rail, TPS, EGR seloind, Cleaned the throttle bottle, clean and tested maf sensor, clean and tested temperture intake sensor, replace the DEPFA(?) sensor. I have replaced vacuum hoses. Everytime I chase a code and repair it another code appears ! )ah) I have reset the pcm and have used two seperate readers to double check everything. Any help would be great, O Also should I just replace the front two O2 sensors and the CAT sensors and then reset pcm and see if any other codes appear?
