o2 sensor

[sean mcmahon]

hmmm ok  So do you know which one peple talk about replacing when they are
getting bad milage?  Ive got a 97 w/2 sensors. If not having an 02 sensor on
the exhaust manafold dosent seam to make a difference, whats stopping everyone
from throwing on the jdm headers?  I think i may have confused my self more now
lol

thanks
