Having the 02 sensor so close to the turbo is not recommended. It should be downstream a little further. If your plugging it into the factory 02 housing your doing it wrong.

It works very well at that place, it only shortens the sensor lifetime as it gets hotter. Nothing a little radiator cant fix.

you could try AEM's sensor test to see if the sensor is still good. Basically you just have the sensor out of the exhaust but hooked up then turn the key to the on position, but DONT start the car! Afs should read super lean, be careful too bc the sensor gets hot. Then dampen a paper towel with brake cleaner and put it around the sensor- the Afs should go towards the max rich. If they fluctuate the sensor is most likely the problem.

Could look up the vid on youtube too, its by AEM and steph demonstrates it
