LT header install... now P0153 code. Help me out
Had my long tube headers installed today. The cars sounds and runs great now but I was pretty annoyed with the fitment. The passensger o2 bung was placed so tight to the starter that the sensor was actually laying against the starter. So what I ended having to have done was plug that bung and drill a new one. Secondly, the o2 sensor broke during the install so I had to get a new one. I drove for about 15 miles with no issues but ended up throwing the P0153 code. I know this code is common after a LT install but I have my rear o2's tuned out and the passenger side o2 sensor is new. I'm not using o2 extensions either. The code is for the pass o2 so what do you guys think, bad o2 sensor?!

, I would swap sensors from side to side and see if the code follows... if it does then replace the faulty sensor but it isn't a bad idea to replace them as a pair

Yes, same exact distance just moved over a little bit. I can try swapping sides with the sensors and see if i get the P0133 code

I will try to take some pictures today. The bung location on these headers are not as far back on the car as some headers. O2 extensions werent required with them. The new bung is sitting just beside the old one. I'm hoping it's just a faulty sensor.

From pictures I've seen it looks like the JBA headers are more like a mid length tube, so the bung being more forward makes sense.

So an update on this problem. Yesterday I decided to check codes on the dic again to see if I had thrown the same code for the drivers side, which ut hadn't. The P0153 code was still on there but only showed as H and not Current. So I cleared the code and cranked the car to let idle... no codes. Took the car out today and did a good amount of spirited driving and still no code! I don't know what's up.

So I keep throwing this damn code. I cleared it off the other day and drove around for a day and a half without it coming back on. I take the car out tonight and after a few mins of driving it came back on. What concerns me is that I am only getting the passenger side code and that is the header that I had to have the o2 bung blocked off and relocated. I am scheduled for a tune a week from tomorrow. Do you guys think ai should just not worry about it or get it back to the shop asap to have it looked at before the tune???

No one has asked this yet so I will. What brand sensor did you use? I wouldn't use anything other than AcDelco or Denso. Denso makes the sensors for AC just repackaged in a Delco box. Stay away from that Auto Zone Bosch junk.

The mechanic working on my car bought a Bosch, from Oreilys I believe. I told him that alot of ppl in the LS world have had trouble with them, so I ordered the AC Delco professional today and will have it put in before my tune next week.

I would re think taking my car to a "mechanic" that would knowingly put in a sensor bosch sensor from o'reilys.

I do wish he had used a factory replacement ac delco, but that doesn't mean he isn't a good mechanic simply because he bought a bosch sensor. He is actually an excellent mechanic and spent many years working for a chevy dealership as a gm master mechanic and I definately trust him with my car. There is alot of shady shops here in my small town that I wouldn't let work on my car for free. Anyway, I ordered an ac delco sensor and will be putting it in this weekend. Fingers crossed that it fixes this issue.

When Lt headers are installed, it's very common to get slow response codes (P0133 & P0153). Also insufficient switching (P1133 & P1153) codes are very common as well with Lt Headers. Just set these codes to no error reported when you have the car tuned.

If swapping out sensors doesn't take of it I will do that.
