Ok I took my 01 Z24 to get it inspected today and my OBD II was not ready (Due to code being cleared) So I drove 50 miles still not ready. so I got the "Drive cycle" from the dealer and I keep throwing PO133 code! I have a header with a NEW ac delco O2! I know that the code is a bank 1 sensor 1 slow response. I have checked the wires and they are fine! Anyone know why it is doing this? How can I fix it? I have a pacesetter header..
Probably need to swap to a heated O2 sensor. With better flowing exhaust on the 2.4's the O2 sensor does not get heated up enough before the car goes into closed loop. Running a heated O2 sensor gets around this. I have done this as well. There is a couple post about this in the performance section.

I have a uneversal O2 that has 4 wires im guesing thats for heat? Where do I hook them up to?
Can I even run the extra 2 wires? They are both white wires.... Please someone point me the right way! I have searched but found nothing! The car is about 2 seconds from blowing up im so sick of it!!! Ha ha
