Hey all,
2004 xterra 3.3 natural 4x4:
So... I had (have) codes PO132 (bank 1 sensor 1) and PO152 (bank 2 sensor 1) both high voltage and PO154 Also a no activity code on bank 2 sensor 1. I cleaned the mass air flow sensor as well and changed both O2 sensors, still getting PO152 code and PO132 . I also reset the PCM (computer). NO black smoke NO fuel loss and... NO oil consumption and no loss of power at acceleration .

Remaining Issues : Idles at 1000 rpm until about 10 miles then drops to 600 rpm, low/rough idle

Recently had a head job (1,000 miles now).
Fuel regulator?Fuel pump?Engine coolant temp sensor?
any ideas?
Thanks,
Ray

FIXED ISSUE**
It was the ground! I made a secondary ground and ran the manifold sensor ground to my negative battery terminal
