Help with codes P0133 and P0153
I've got Dynatech Supermaxx headers with the Random Tech cats installed about three months ago. These codes just came up. I cleared all the codes and they came back immediately. What is going on?
Thanks.

I had this problem with a set of SLP headers on a WS6. Exact same codes. Check for LEAKS and burned wires first. Did you move the rear o2's to the front position? Apparently these have better heaters in them to account for less heat downstream. If it is true it should improve response time and Long Term Fuel trim switching.

codes
I had the same codes under similiar circumstances. I called LGM and they told me immediately to search for possible burned O2 sensor wire.
Sure enough there was a wire touching the exhaust and it had burned through the outer sheath and the insulation of the common ground (black) wire. That common ground wire operates both O2 sensors which is why I got both codes, right and left sensor.
Jack it up and look for a contact/burn on a sensor wire. I wrapped mine in tape and pulled and pinned it way out of the way of the headers, making sure there was no contact anywhere else. No problem since.
