P2A00 SES code
#21
UPDATE:
I removed the CAI intake and put the stock one back on. The CEL came back on after about 100 miles this time. So, I'm left with one final thing, the HFC. I will take your recommendation about the gaskets and will inspect them before making the change.
This is driving me crazy!

UPDATE:
Up to this point, i had removed my plenum spacer, CAI and now the HFC. The gaskets were all in great condition and I observed no leaks whatsoever.
The stock cats have been on for over 250 miles now and no CEL! After jogging my memory once more, I remembered that the CEL did come on after the HFC were installed on my car before all the rest of the mods. The car drives great and my observed mpg is ~23.8 while before removing the HFC, it hovered around 21.0 mpg. I will be reinstalling the spacer and intake in the next few days.
To Onagao:
In your sig it says that you have ART pipes. Im assuming those are tp's? Try to remember when you first saw the code. If I were you, I would replace the tp's with the stock cats. I'm beginning to think that its the excess vibration that could be causing the code.
Thanks, hope this helps.
I will post another update after a few hundred more miles.

UPDATE:
Since my last post, I have removed the HFC, installed the stock ones and put the spacer and intake back on. I have driven around 3000 miles and no CEL!
The HFC were the problem afterall. I would have loved to fix this problem, but after searching and searching, I found no solution.
Hope this helps anyone else out there with this issue.

Well, I'm really happy for you. That's fantastic. I can only imagine the relief it must be.
So to clarify - you don't know exactly what the cause was, just that the replacement fixed it?

Dude, I would be all over that if I still had them... I gave both my stock cats and my Stillen HFCs to my brother in New Mexico. So I've got nothing to put on there. Any ideas?

Sounds like this is a common problem from 350Z cars. I was told that my needed a air flow meter then an O2 sensor...after being only 3 yrs old...i doubt it was really the part that needed changing...
So the part was ordered after waiting for over a month for the part to arrive from Japan.. and then fitted by nissan...after 430km i am still having the same problem...
The same code is still showing... and the car definately feels sluggish when the engine light has come on the dash.. even though the code has been reset and taken back to nissan again...
Not sure what the hell is wrong with my 350Z... have anyone found a solution to this problem yet..?
If Nissan can't rectify this who can ?
