something weird is happening

[97NYstanGT]

on my way to autozone i got 2 codes (system is running too rich in both banks) even though on the dyno it showed that the car ran too lean, i reset the codes and 10 minutes later i got it again. reset the computer to stock tune(started to sound so much better) and it started to over heat and threw out 3 codes, system is running too rich on both banks and P1000 which i still didn't figure out what it is. so i set it back to BBR tune. runs cooler now, but still throws out the rich codes. whatta hell is wrong with it?

Not really sure, I will do some recon for ya, but the p1000 code is OBD-II Monitor Testing Incomplete, it just means that the OBDII system check has not been performed. In other words you cant pass emissions until its gone....other than that it means nothing. Will find out more.

but idk why it tells me that the car runs too rich and i know that i runs too lean which is dyno proved and i'm trying to find a solution for it

check your oxygen sensors or could be something else wrong, and or get a CUSTOM tune

i thought you were going to say your voice is cracking lol

either o2 sensors or bad tuning.

oh you're on here too? i already ordered a pair of oxygen sensors, and already bought a new fuel filter. that will go on soon, and i can't afford a dyno tune now, so i have a mailed custom tune

I would doubt it is O2 sensors since it is happening on both banks. It was leaning out on the dyno? So, you had it dynotuned? What was causing it to lean out? Was it only leaning out during open loop?

mailed custom tunes are hit or miss. your probably better off not running it right now until you get this thing under wraps.

by the time you spend all the money in figuring out what may be the problem you'll probably up to the cost of a tune or close to it.

my mailed tune was 100%

like i said they are hit or miss. BBR is great so I dont doubt the tune is horribly off. Chris at blow by always give me great advice, but every car is different and some react differently then others.

got mine from brenspeed

this morning i changed the fuel filter and one 02 sensor, since i only had one, on my way from work it threw only one code PO172 which is reach system bank 1, i put the 02 sensor on the passenger's side, so at least i know that the 02s are the problem
here are some pix

look how much thicker the new 02 is

 

[97NYstanGT]

well, after changing 02's and pcv valve i ended up spraying the MAF and that solved the problem
