Never really ran into this before with the o2 sensors not readying on the emissions tests. The car is a 96 24x swap. Brand new ntk sensors...logging shows the car going into closed loop...o2 sensor swings look reasonable thought they made need alittle work because of the longtubes but everything seems to be in order. They do have extensions but I'm seeing no issues via the logs or anything. Is there something I am supposed to do for these tune wise? I am using normal 96 o2 sensors which I am wondering is the mistake. Thanks guys.
