With GREATLY APPRECIATED HELP, I've taken care of all codes it was throwing, but there's still another that I can't figure out. I've got a 94 SC and it's giving a 172 code.
The EEC IV code book reads "lack of O2 switches, indicates lean rear side."
Is this telling me that there is a 3rd O2 sensor at the rear cat? If so I can't find it. Besides, I thought that I've only got 2 O2's, one before each front cat. My exhaust is all factory original.
Please help!!!!!
Thanks,
Alan
