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.

 

That does sound like it's running rich.

Does the car have factory cats on it?

 

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 you'll get times when it will read badly on the O2 sensors, reset them and see if it improves, otherwise you'll need a tune to write them out.

 

how should i reset? just ecu reset?

 

Yup, iirc, that clears codes too, or just get autozone to clear it for you, will only take a moment for free.

 

Thanks haha and any idea how much 3,4, and 5th synchro rebuild would be?

 

A new gearbox i think.

 

What year/model Z do you have?

 

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.

 

new trans, cd009 from z1.......

 

Found out the problem my bank 1 upstream sensor was almost sheared off only half the wires were connecting thanks for the help guys!!
