Hi all, first of all loving this site, I've had my Z for a little over a month now and my SES light just came on. I am having a problem with my O2 sensors on bank 1. Got the codes it is p0132 and p0152. They are both reading rich. I have a borla catback and a jwt pop charger. Was wondering if my car is actually running rich or if there is more too it than just the sensors. Car seems to be a little worse on gas mileage and slight smell of gas on cold start at times and sometimes white smoke from exhausts. Car seems to have a little less power but could be me over thinking. Let me know if anyone has had this problem fixed.
no it has the borla cats that came on the exhaust, and the O2 sensors are reading rich on bank1. Sensor 1 and 2 on bank 1 both reading rich. and bank1 Im pretty sure is the passenger side.
So what exactly are the readings for sensor b1s1 and b2s1 then?
Downstream sensors (behind the cats) should be pretty steady. If they're reading all over the place then you would likely need a new converter.
