Damn. CEL P0159 P0139
Today driving home on cruise control car threw a CEL and the traction control light. Ran the code got the above PO159 and PO139. Do these codes pertain to what O2 sensors may be bad?
I put about 5,000 miles on the headers which were professionally installed at ISHII Motorsports in Bellevue, Washington which is very far away from home.
I did happen to pop my gas lid and noticed that when I turned my cap clockwise it clicked (i did fill up on my drive home) tight. I tried to turn it again to see if it would keep clicking but it wouldn't... so Now I'm wondering if I just left the cap loose...?

I would clear the codes and then disconnect the pos and neg side of your battery for like 10 min then reconnect and go for a little drive and see if any codes come up.
I believe this iis a problem with the o2 sim... My friend had the same issue on this ppe headers.

I think if you contact ppe they can help you out as this is probably an issue with the 02 sim

Well I left the battery unhooked overnight, drove it 30 miles into work this morning... No probs. Bummer though, I'm sure it will come back. I'm due for an oil change this weekend, I will take a look when I'm down there for exhaust leaks and things I guess.
The only real pain in the *** is the shop who installed them is 2 hours away, just a huge hassle.

Did they install the o2 conditioner/sim?
I got the same codes all the time when my exhaust was leaking(custom test pipe/cats) with the PPE headers and o2 conditioner. Once I shored up the leaks havnt had them since.
The PPE o2 conditioner is still sniffing just not as sensitive as stock, you dont want leaks and you want it installed properly.
Reset the codes, it might be a fluke

Disconnecting the battery to reset the ECM is unnecessary. Just pull the EFI 1 fuse and the ECTS fuse and you're done. You won't have to reset all the windows and the sunroof, nor will you lose all the other presets.
See this post for photos of the 350 because the F is almost identical for resetting the ECM.

Thanks guys.
The shop has worked on previous header installs on the ISF, and the owner was once a Toyota master tech, I trust that he installed it well.
