I had purchased O2 simulators but I was getting codes. I removed the sims and have been good since. I am running AAM test pipes that already have the spacers for the O2 sensors.
The HR is known to be very finicky with O2 sensors.
I get them every 3 cycles or around 50 miles....both sensors. I have OBD reader and an iPod installed...I just turn it of until full exhaust is done and the tune to solve it
I used Berk test pipes. They have the "built-in" spacer. The CEL comes on every 8k miles or so. I clear it with Torque App and it doesn't bother me for a few more months.
