hey guys, first post...howdy.

throwin a p1166 and p1167...and i searched...its the air/fuel metering. I've searched other forums as well and everyone pretty much says its probably the O2 sensory, just wondering if you guys had any input.
Which O2 sensor is that? and where could i get it cheap. From what i've read my best bet is going oem because the other ones arent trustworthy...true?

thanks in advance.
peace
