Ok currently I am throwing codes. They are 3 codes basically saying that my O2 sensor is damaged and malfunctioned. It's been like this since I got my cat-back made (for a long time).
I wanted to know if this would effect my performance. I was talking to a friend (you know who you are) and he was saying that it could retard my ignition timing and possibly make me run rich.
Is this true?

the downsteam or upstream?
H O N D A, oh how well love it when we smokin V8s, all day, every day, it dont stop, Im rolling in my Honda like Im running from the cops.
BUT Now you know, cause you're Jon Doe, in a black bag, a tag on your toe, I built the Honda, I felt the pain, you're victimized with no one to blame, you're just another victim kid.....

NO it will not hurt performance.

just make you an 02 simulator & the CEL will go away.that way when somethings really wrong you will know.

yeah the after cat o2 only measures the fuction of the cat
I'm throwing codes for bank 1 and bank 2. Does that mean BOTH O2s? I have the sim on the rear one but I still have a code for #2 O2...WTF?
....fuuny, I have had the saaaame problem. I get my upstream 02 sensor replaced, like, every oil change it seems, b/c I keep throwing cels. it's b.s. i get it scan-tooled, it comes up as a bad 02..i replace it, reset the e.c.u., it is fine, for , like, 1000 miles..then same problem. cars have too many electronics, these days, lol.
but hondakilla, to answer your ?...I dunno if it will or not.
...don't hate!.. respect people that have talent, even if it is in something you don't like or understand.
the one that monitors the cat, can affect the entire system....
if its saying the cat is bad, broke, malfunctioning, then the computer will tell the first sensor that there is a problem and that things arent efficient.
it doesnt have a direct effect, but most times the cel is thrown, something performance wise will be affected.
whole car is like a system like the human body....
if your liver starts to fail, your kidneys retain water and have to process more crap, meaning for everything that fails or malfunctions, it goes down the line and affects something else....
how the hell do you make your own after cat o2 sim????
Coming soon to a SoCo Area!
(no its not a car club)

Just because it throws a CEL does not mean it will hurt performance. There is many codes thrown that does not hurt performance. I good way to know is if the fan is running, while the CEL is on, and no A/C is running. The Fan will run when a sensor is messed up, bad, out, or something is wrong that will hurt drivablity.
For instance my up stream O2 sensor is bad, and my fan is running because of it. I can tell my car is running like crap as well.
I have not cat, and a O2 sim (RK one), that does not work worth a crap so I have a CEL for that. Before my up stream O2 went bad only the CEL was on, and no fan running.
Foe the guy talking about replacing his sensor every 1000 miles. What brand sensor are you using??? AC Delco? Bosch?

is the code catalyst efficience under threshold?
my 98 z4 cavy is throwing the same codes

well for example, dtc137, fan will turn on.... basically a low volt malfunction... 138 which is the high voltage of sensor 2, fan turns on....
140 which is insufficient activity, the fan should turn on as well.
the most common its seems from the maintainence forum is 141, the heater performance doesnt work....
however thing is..... for that one which is the most common, it runs in loop till warmed up.... if the sensor isnt reading as it should, and a cel throws, something will be compensated....
just because it doesnt effect you instantly, doesnt mean it doesnt affect performance. same goes for ebay chips or iat relocations....
doesnt effect most instantly, but over time is when stuff degrades.....
for every action theres an opposite reaction.

I will check my codes today and post what one I have (that has not been turning on the fan). I have yet to see a code for rear O2 sensor turn the fan on. I have ran without one , no fan, ran with the sensor hooked up (no cat), no fan, and with the Sim (that does not work right), no fan. I know I'm not the only one either.

you can post em...
ive already ran with bad cats and damaged o2 sensors as well.... the second one as well as the first... the fan turning on are one of the things that CAN happen when the code sets. thats straight from the gm shop manual. for some it will, for others if its not critical, then it will not.
fan usually comes on when drivabililty is effected, say like misfires....
the cel lights are like stop lights...
1) light comes on, your still in the green, just get it checked...
2) fan comes on with the light, yellow.... be cautious and get it home and or checked soon.
3) blinking CEL light.... something is wrong, pull over, red light, stop soon and get it checked/fixed.....
but on the second one, the effect of running with a bad one or a malfunctioning one, is basically the same as the ebay resistor mods....
doesnt affect performance right then and there, but over times things degrade.
as for o2 sims, not big on em if you (in general) run a cat.... o2 sim wont tell you when or if your cat goes bad and if it does go bad, performance slowly decreases. and some on here in the maintainence forum didnt know until they couldnt figure out why their car didnt start and stay running.... completely clogged converters were the cause.... most all ran o2 sensors...
for you running turbo and or no cat, then you have nothing to monitor, however for those that DO run cats, i wouldnt personally even suggest it.
if you have something on the car (your not included since you removed yours, so theres nothing to monitor) that comes with its own built in monitor, you;d be a few fries short of a happy meal NOT to take advantage of using it...
Ok I had checl the codes, had one for my upstream sensor (it was bad, and Iknew that). Fan was running fro it. Cleared that one. Got one for the rear sensor, for insuffecient activity, or something like that. No Fan. All is fixed anyways. I put in a new upstream sensor, and I made a manual O2 sim. Stock sensor is still in the exhaust, but will not throw a code since I have not cat.
I agree if you have a cat no need to worry about not having a sensor or not. I do not have one (for performance reason's), so I had to do a O2 sim. I would recommend not buying one of the $80 ones, because they suck!!

I have clogged my Factory cat twice and both times I never got a service light or nothing. I just figured it out. Well IMPHAT figured it out but that is besides the point.
When I got my High Flo cat because i was getting tired of Clogged Cats and the fact that I was out of Warranty. I get the Service light thrown about 1000 miles after I get it cleared.
But here soon I am going to get that o2 sim.
