O2 sensor question and P0135 DTC. Alright guys I found a new problem after the SES light came on. I have a P0135 failure in the heating circuit for my O2 sensor on bank 1, first of all does this mean that the sensor is out or something else.
These are both new AC Delco O2 sensors that have seen maybe 10 miles on them, but they are on open headers at the moment. That brings me to my other question, will open headers foul O2 sensors quickly? I am going to get exhaust put on soon, but I'd like to know if my headers are doing it or if there is something else.

Looks like it may be due to my longtubes. I've checked and more than a few people have this problem. I'm gonna swap the sensors with the other side and see if the code follows banks.
