Alright. I changed the exhaust manifold gasket and while I was there I installed a Banks Torque Tube header, be nice. After I put everything together I started the Jeep and immediately got two codes that will not go away. P0032 and P0052. I know they are for the heater circuits I believe for the top two O2 sensors. Could it be that the sensors decided they did not like the header? I have all 4 NGK waiting for install should the need arise. Wiring is good. The Jeep only has 28,000 miles on it. I'm really hoping the pcm isn't bad. I do know the PCM is bad on the charging circuit, but I bypassed that. Thanks!

New sensors same problem. Guess I'll check wiring. I need to find a schematic.
