Nos killing O2s!
I have a NOS dry set-up with 125 shot on my 98Z. I have been running nitrous for a while, no problem. I just got a off road y-pipe so I am not running any cats. After the y-pipe, I sprayed and killed the 02 on the passenger side (the upper 02, on the header). Then I replaced the odl factory sensor with a bosh, sprayed again and killed it! WTF..am I running lean on one side? Could it be a bad fuel injector? Its only the passenger side on the header. I do have sims replacing the back two. Has anyone ran into the same problem, cause these sensors are not cheap! lol
