Hi guys, Did an OBD 2 scan of my 97 Ford Explorer v8 5.0L. It came back with the following codes. PO304 ---------cylinder 4 misfire PO153 ----------O2 circuit slow response bank 2 sensor 1 PO133 ---------- O2 circuit slow response bank 1 sensor 1 PO171 ----------System to lean
I am looking for a couple of pieces of information that maybe different people may have experience with.
- Do all these put together indicate one problem or multiple problems that need to be addressed
2.The O2 sensor has not been replaced since I have owned the truck in
2000 so I imagine that outside the misfire on cylinder 4 these are overdue for replacement.A) Are the O2 sensors the same in all locations or are they different types, (i.e. can I order 2 of the same or are their differences between the O2 sensors located in different locations of the truck.
B) Anyone knows a website with pictures of the locations of these sensors, or can describe these locations.
Any advice or how to's is greatly appreciated.
