i have a turbo'd d16z6 and its been running great for a while now but outta nowhere a couple of nights ago my a/f gauge started reading really lean,i got a #43 code(fuel supply system) but only once but it hasnt came on since...i changed my fuel filter and fuel pump...and its still reading the same...im scared of detonating so im not driving it although it still runs fine....does anyone know why its doing this or what other things i can do to trouble shoot the problem...i was thinking about changing the injectors also,im running stock ones

Re: please help (vxHATCHATTACK)
hatchattack...I had the same problem. I would drive and all of a sudden it will go to red on my af gauge. I pulled the code and it said fuel system blah blah blah. I took my o2 sensor out it was all black. Im guessing it was out for the count. I pulled a o2 sensor from my old dx motor put it in my ls. I never seen that CEL again and it never read lean on my af gauge. Hope it works the same for you

If you need to go somewhere you should be alright if you keep the RPMs low and out of the boost. When I was driving untuned my a/f gauge ran dead lean sometimes (sometimes even off the gauge, if u know what i mean). To solve my problem I would just turn the ignition all the way off and on and then back on (while i was rolling or something so I didn't have to restart). Hope this helped in any way.

No problem. Did you post this originally on a friends account or what? your name changed. Let us know if you find out the problem. o2 sensors are like $60 btw. Usually bad o2 sensors turn on the check engine light. hmm.
