hey guys, just having a little problem with my sr20det, since i bought it i replaced the fuel filter to a 300zx tt. kinda got rid of really bad sputtering at any rpm. but now it stills sputters a little bit at idle and sometimes at low rpm. i feel as if power is gone at woot passing 5k. feels like its running lean.

it's a stock SR. anyone know what it could be?

could be an o2 sensor.
