JPP Header problem

[808Camry]

I just installed the headers today that I bought from Castro (thanks!), during the install the rear headers was a biach to take out. Once that was out, the O2 sensor was melted on, probably from my running too lean this whole time with my SC. We busted that out and just bought a new bosch one without the harness plug. So we then stripped the wires connected it as to how it was stock, no prob there. Then getting the rear set on was a biatch too. Finally everything in we started the car. About 30 seconds later after the car runs through its diagonosis I guess the dreaded CEL came on giving out a code P1135 (Air-Fuel Sensor Heater Circuit Response Malfunction). No idea what that was but the scanner said it was just a code and that it was ok to drive. Any idea as to what the prob is and how to fix it? And should it be okay to drive if I keep it easy?

Other thing is there's this slight raspy sound coming from under the car as I depress the gas pedal more. Like a bead bouncing around in a coffee can.

Sorry for the long post.

Other than that they look beautiful and trippled the exhaust sound. It now sounds like a turbo STI. I'm happy so far, just need to fix these minor bugs.

glad to see that everything worked out fine Ron. Good luck with the camry project.

FYI in case anyone searches this I found out today that the P1153 code means the bank 1 sensor 1 air/fuel sensor is bad. This is the sensor located behind the engine on the rear exhaust manifold. When I installed the JPP Headers the stock rear air/fuel was melted on the stock manifold so we bought an O2 sensor thinking it was the same thing. Well I now know it was wrong. So just replace with an OEM one if you ever run into this prob and you should be fine. Hope this helps anyone that searches for it.
