Hotshot headers and o2 sensor (quick question)
I installed the second o2 sensor BEFORE the cat on the header, I expected to get a check ingine light but I didn't. TOday i had it placed behind the cat, and replaced it w/ a new sensor. Could it be that my wiring harness is malfunctioning because I didn't get a check engine before? thx!

It's supposed to go after the cat. That's y it's weird, i should of goten a light since the ECU would of thought that i was running too rich or something, the wiring is clean, the harness reached all the way to the new location so I didn't have to cut it. thx
