So when i was putting in my headers and exhaust I took my car in slowmotion motorsports to get my second o2 welded on my new headers. They told me it would be more efficient to just to rewire the primary o2 and place it in the flex pipe where the secondary usually goes. Now my problem is got these codes po134, po136, po141. I believe two of them are for the secondary which is okay because I only have a primary o2, but the other I believe is telling my primary o2 sensor is bad. Which it could be cause I did put quite a bit of force on it to get it out of the stock manifold. As my car sits now it idles and bounces of 1500rpms on start up. Any opinions?

 

Don't listen to those idiots. Get you first 02 wired where it should be before the cat, and get your 2nd 02 wired in after the cat.

 

Well im running catless and I just want it to not run like a pos, like it is now.

 

If your catless, then you need to do what i did and go to an auto store and pick up a pair of sparkplug non-foulers, and screw your oxygen sensor into them. Thats the only way I know how to keep the CEl off if your catless.
Like so-

Thats a good idea but will this fix my idle problem?

 

Probably not.

And there is no way to put a o2 bung in a flexpipe. What do you do, weld the bung to the individual strands of flex? LOL

 

Thanks redz..... But no where the o2 bung is located in this picture on the pipe. http://nopi.com/dsp_part_detail.php?vnopinum=251+2862 But really any solutions for the high idle. Bad o2? wiring problem?

 

I see where the o2 bung is on the mid/downpipe there. What about it? You need one o2 bung after all 4 pipes come together, which you have from that picture. You then need one after your CAT to show a difference in readings. If the readings are not different enough, you get a CEL.

High idle is easy, adjust your idle control screw on the back of the throttle body.

Did you reset your ECU lately?

 

Not since exhaust I shall do that. Also about the code, I got a po134 so I was wondering if my o2 sensor could be bad, considering i used a torch to get it out of the stock exhaust manifold. Thanks

 

It sure could be bad, I'm not sure what that code means, and I'm heading home, so I can look later. If you are running no cats, expect CEL's and therefore running issues, unless you do the side fixes to get past it.
