Its a 2002 supercharged Xterra 232000 KM on it, 2000 K on brand new rebuilt engine.
p0132 and 152 codes are o2 sensor 1 curicuit high, both banks..
It all seemed to start after I ran seafoam through the fuel system (I dumped a bottle in the gas tank before a fill up) I have changed the 02 sensors, they are NTK not OEM. and the code used to be thrown every couple 100ks of driving, now its appearing more frequently and more often.. So I changed the fuel filter as well as cleaned my maf sensor (I have a K n N filter which I hate) and yet it still keeps coming back..
My nissan buddy seems to think its more than likely that the computer doesnt like the NTK o2 sensors? and I can see his point, if it were the fuel injectors it wouldn't run as good as it does in open loop.
It sometimes gets to a point where it will idle rough but then it pops the code goes back into open loop and run perfectly fine so I can see his point that it might not be the injectors..
what are your guy's thoughts?
small Vacuum leak?
anything im missing?
