Haven't replaced the o2 sensor yet, still having cel periodically from that particular sensor so I am fairly certain that it is the sensor. Sometimes it is a slow heating code, sometimes an out of range code. Never consistent which tells me it is the sensor. I have another one to install, but have been busy having the new suspension installed.
Fwiw I did the bilsteins and h&r springs/sways with tarett drop links. Will need rear toe links to get less than 2 degrees of negative rear camber, but the stance and handling are amazing. As a non track car it is just awesome. Sure pss9 is better, but I have zero complaints. Pics soon. And I will figure out the exhaust and sensor issue and update everyone.
