Okay. I'm ready to strangle my dealer...
I have a recurring "check engine" light CEL. It has only begun in the last 2k miles (36k on the odometer now). I have brought it to the dealer three times--the last for a 2 day stay, and it still is not solved. It will go away for about 3 or 4 restarts and a half a day, then mysteriously comes on.
All of my mods were done A LONG TIME AGO, and never have I gotten a CEL before (headers, cai, tps, ypipe, cats, grounding kit--things that might have some affect). The code is flashes is P1273 defective a/f sensor Bank 1, though bank 2 is entirely unplugged. The part is the 22693-CD700 heated oxygen sensor. It has been replaced twice.
Now, about 6 months ago my gas cap supposedly was loose and caused my whole car to freeze up (see old post) cutting all fuel over 1k rpms and I was stranded in Tampa. It was attributed to the gas cap only, reset, and the car was fine. Every time I have brought it back in, they ask about the gas cap again.
The car itself runs fine. I believe I may here a slight exhaust leak on the right side near the yipe/cat, but the dealer said they checked for leaks and found nothing.
Anyone have a freakin' clue what the deal is???

I did a quick look and found a Nissan Bulletin available for the P1273 DTC code. It mentions several things that can cause this code to go off. Exhaust leaks are one of them.

Interesting reading, but nothing an Infiniti dealership should not already know. Hope this helps out some.

Interesting... I hope you get this fixed.
Wouldnt the exhaust leak have to be from the cats, forward. Since there are no sensors from the cats back.
I've heard reports of headers having issues with their flanges not being true.
Bad gasket maybe? Wouldnt hurt to retighten your bolts to spec from the headers back.
