got a check engine light and hooked up an obd scanner. result was a defective o2 sensor #1, which is b4 the cat. conv.. where can i find the o2 sensor #1 on my honda prelude 1998 ( standard ). i've looked on the manilfold but it's not there, is it further down the manilfold. do i have to bring it to a mechanic to fix this or can i do it by myself. thanks.
