Western Members - Service engine light?

my service engine light came on yesterday after racing a 350Z. I scaned it the code today at autozone and it read 1out of 2 but it wasthe same code.P0430 catalastic efficiency below threshold(bank2) anybody know whats wrong? 02sensors or cats?I deleted the code and its been of so far but I am afraid it might come back. does this affect the cars perf. in any way? should I get this fixed ASAP? :confused:
thanks!

Had the same problem as well, I think it was the racing gas that I had been using off and on for a couple of years, It glazed the cats. Simple way out is by punching out the cats and getting sims or just deleting them. Just my 2 cents

LOL @ car catching bird flu....

Must have been the 350z that gave it to you...

it's O2's or a bad cat...

Thats the downstream O2 seeing if the converter is working properly thats what its there for.How many miles on the car?Possible your converter is starting to used its life up or starting to plug up.


But just like Chad said punch em out and use some sims until smog time :devil:

i had the same code about a month ago . .i read the code. . deleted it still hasnt come back on . .101 every thursday and still hasnt come back on . .i would gut mine but i dont want to draw more attention to my self. .

Why are you guys running race gas? Are you running like 200 + shots of nitrous or bad tuning or what? I run 11.5:1 compression and a 150 shot without needing race gas (no detonation). I also don't get any better times by running it. Of course, my car is tuned for nitrous. I just hate to see you all waste your money on race fuel if you don't need it.

As far as your code: I would replace the back right O2 sensor and see what happens.

i dont fill my tank but if i know im going to be spraying alot that night i rather just have the added protection whats 20 bucks of 101 just for peice of mind. .

Good to go. Yep, a little bit will keep you safe. Alot is a waste. Smart thinking.

i didnt go to high skewl for 7 years for nothing
