02 sensor...help

[raisinbran88]

hey everybody, i need a question answered, hopefully somebody can help. ok so i took off my stock exhaust, put on headers/downpipe and a megan cat back system. the stock cable for the 02 sensor was about 6 inches short of reaching it. i got an extension for that cable from a buddy, but i havent connected it. i do have a check engine light goin off, which i knew would happen, but i was wondering....is driving without that 02 sensor in place going to cause any problems? i still have the primary sensor plugged in at the downpipe, its just the secondary thats unhooked.....so just wondering if its going to cause any damage if i run my car without that sensor...any help answering would be appreciated.

running without the secondary o2 wont do a thing to your car, just that annoying cel

exactly

yeah rear o2 only monitors the catalytic convertor, to make sure its still functioning properly...no harm or change will happend to engine performance if that sensor is not plugged in...only thing is a anoying check engine light, and not passing state emissions tests...

Hi everyone new here!! So say someone removed the cat and replaced it with a strait pipe. Of course it threw the dumby light, is there anything that can be put in to get the dumby light off so the remote start with work besides the cat. The second sensor was put in the new pipe. Thanks everyone!!!!

modifying spark plug fowlers for the o2 sensor has been known to work as it takes the sensor out of the direct path of exhaust and "fools" the sensor into thinking everything is fine. or you can get it tuned out.

Im not much of a car guy, more sportbike LOL. Whats modifying spark plug flowers or how would you go about doing this. Then tuning it out would'nt that make the motor run lean. How this whole thing started was the flex part on the down pipe broke. I replaced it with a weld in ebay replacement, well as I was in there I thought well lets try and get some more gas milage and took the cat out. Not thinking I new it was going to through a dumby light but didnt think the dam remote start wouldnt work. So here I sit GLs ankles broke, its getting cold she wants her remote start. Ya I know dumb move!!!! Should have just replaced the broken part!!

 

[outtamymind]

well your rear o2 sensor shouldn't have anything to do with your remote start. i'll explain more when i get back. got to pick up the mother as she hates winter driving

Thanks for the help man!!!! When I clear the check engine code everything works and the only code that comes up when plugged into the scanner is the emissions code. So its got to do with the check engine light, some safety thing when its on. Everything else on the car works great!!!!

ya could be. been a while since i've had to deal with customer remote start problems. either way get it tuned out or put in a spacer which is what the spark plug fowlers are

 

[deanozx10r]

Where would i find these spacers and Im guessing these go on the o2 sensor pulling it out from the exhaust flow?? Or can I just through some washers in and that be enough?? Or if I go the tuning rout how much would that cost and would that give it more power and better gas millage??

 

[outtamymind]

well tuning depends on the tuner doing it. and the fowlers should be found at any parts store. the thing about it is you have to drill them and thread them if i'm not mistaken

Any autoparts store should have them around their nuts and bolts section. Bought mine at O'rilieys. They may be labeled as "Spark Plug non fouler"

The ones I bought you didnt need to drill or thread.

 

[outtamymind]

oh i may have misread that somewhere. thanks for clearin that up

 

[YelloEye]

Just make sure you tighten the fouler onto the o2 sensor before you put it back in so as to not mess up the o2 sensor.

oddly with my full exhaust setup with the highflow cat i've only gotten the p0420 code 3 times in the 2 months i've had it on. get more p0171 codes then anything

Thanks guys very helpful!!! I'll check into this, the exhaust is all stock except the flex piece and the strait pipe that I replaced the cat with. It gave it alittle growl to it.
