hey mates, I jsut bought a used 350z radoster 2004. it needs a little work but a i got it very cheap.
I ran the auto zone codes and it came back with these codes:

P0138
P1148
P0158
P1276

this car has a really cheap aftermarket air filter on it but no other mods.

these codes indicate that both bank 1 sensors need replacing and bank 2 sensor 2.

could it be that all three snesors are indeed bad or could one bad sensor throw the others?

thanks so much for your help!
