I have cleared a 1-7-5 twice now,
I'm hoping my lowering the boost when my belt gets here will cure this. Read about the 1-7-4 where is the list?

I found this cool website that will allow you to enter the code:
http://www.actron.com/code_lookup/index.php
P0175 = System too rich (bank 2)
P0174 = System too lean (bank 2)

Awesome, better rich than lean!
Big sigh of relief.
Turn the engine to run where the dash lights come on.
Count 3 seconds (you need a watch it is exact.)
after 3 seconds press the accelarator to the floor then release 5 times in 5 seconds
wait 7 seconds
push and fold the acclerator to the floor for 10 seconds until the CEL starts flashing.
It will then blink 10 times (trust me w/o a watch it won't work)
Count the blinks, after 10 count the series of 3.
So in my case it goes like this
3 seconds on
5 seconds push, repeat push
7 seconds wait
10 seconds push hold
10 blinks pause
1 blink
7 blinks
5 blinks
then the blink cycle loops again starting at ten
To clear press and hols the accelerator for a full 10 seconds then release
then turn key off then restart, CEL is gone
Peas!
I use the Nissan programming built in found on ther CD there are all kinds os thricks in there like resettting the MAF andf TB PS etc

Oh I forgot, Zzzya thanks man!
I am damn impressed that my stock fuel system is keeping a 10 pound FI setup rich. I have larger injectors and am off boost until
I get a new belt, then I am sure I can resolve this but I was thinking worst case scenario i t was a lean bank like 174 was. Bookmarked the link! Very good day today!

could it be that you're too rich due to off being FI?
I haven't went WOT or above 3k rpm's since hitting over 800C on my EGT with EJ haha we made a WOT run at 10 pounds several times and when I saw the warning light I decided to chill.
I am very confident that when I get to 9lbs and drive it like I normally would an FI car it will go away and I have ZERO concern about this light now that I know what it is.
Even before I wasn't real concerned because the car runs perfect.
When driving it on bost daily I never got the light, not until grandma driving. It hasn't come back in two days after I cleared it.
Did you Check engine light come on??
It came on again after 2500 rpms all day lone (it's an A5T.)
I counted it and sw 175 again, knowing 174 was LEAN I became MORE concerned, knwing what I know now I am comfortable with what is occuring with my 02's plus I have RT's.
Plugs are fine.
Peas!

It's like a 25 dollar OEM CD that no owner should do w/o.
It has everything you would ever want to know about your car.
Consider it to be the equivelant of about 10 Chilton manuals in CD-ROM format. They are floating around everywhere and it has helped me allot like when reearching after market fuel pumps people were posting schematics from it (I think it was teh215) Kido's to him mang....
I got mine here somehow, forgot where.

I think it is the same one 12secz is talking about. If it isn't, please let us know. This is the only manual I could find. The only problem I have with it is the fact that there is no index to the pdf files, just a couple letter title.

Almost as important as the code is the freeze frame data that is stored along with the code. This will tell you the exact parameters occuring when the code was set i.e. LTFT, calculated load value, etc. Unfortunately you need a scan tool to have access to this info. If you are getting a po175 especially after a po174 (both bank 2) I would suspect maybe an O2 sensor going toast or at least getting a little lazy in the cross counts. I wouldnt sweat it too much if it only occuring under light thottle conditions. hope this helps....

Yeah TS has one of those it gives more info too.
I am not running as as rich as some may think it's just these 02
s and the ECU is so smart with learning etc.
Judging by my EGT's and tail pipes and plugs though it's fine, I just need that belt to add the right pulley, it may come in today.
Worse case sceraio is add the pulley and go back to TS and flash at 9 instead of 11 I am 100% sure they would take care of me they always have.
After I get the final 9 lb readings on my boost guage and feel comfortable I will do some more Dyno pulls at Marco's on a Dyno Jet and post my A/F numbers. Thanks everyone.
