I am throwing a P1133 code and already tried swapping the O2 and I got the same code. I did recently have a hot day where the idle stumbled a few times and then the code was there a few days later. I also have a tank full of 100 octane UNLEADED racing gas.
I think I may have seen a carbon trace at the drivers side header flange. No tick though. They are Kooks LT's with no cats. I deleted the rear O2's with my HP tuners.
I don't know how to read the charts but the O2 in question does jump way differently that the passenger side . even after swapping out the O2 with another factory one.
