check engine

mmvi · June 4th, 2007, 08:05 PM

my check engine light is on. the code reads : bank 1 rich, bank 2 rich (P0172, P0175). I replaced my spark plugs and my plug wires, but it still continues to come on. I am due for inspection in a month, and I'd like to know what else this could be.

your running rich you done any timeing or a/f changes or changed any engine components?

mmvi · June 5th, 2007, 05:41 PM

my car was completely stock when the light came on. I've been turning it off with my tuner, but it's annoying. It usually only comes on when I reset my battery. my list of aftermarket things is below.

Id say something within the exhaust triggered your sensors to go haywire. Just like mine. Now the light is going to stay on until the thing gets fixed. When the light comes on, your fuel/air ratio gets taken off its default setting and the car starts to take up alot of fuel all at once. Which is now why youre getting alot of rich codes. And itll contunue to stay this way until the problem is solved. Start troubleshooting...

how many miles and have you ever messed with you O2 sensors? sounds like you have one that is going out...

i would know... mine finally went this morning ... on my way to the shop... they tried to clean them a bit and cleand the MAF and IAT for 35 bucks... not a bad use of money.... now my car doesn't bog in the lower RPM's so have that looked at and give your sensors a good cleanin

try fixing the problem the right way or go the cheap way and buy mil eliminators. that way the engine thinks the air is fine all the time

Ive done so, also, and sadly, still dont work. And even went above and beyond to find the problem for them not working either. Had the MILS in the front and the extensions for the sensors in the back installed, light stayed on. Switched them both so that the MILS were in the back and the sensors were in the front, light stayed on.

Then again, driving around with a computer that "thinks" everything is fine isnt really a smart way to go about it either, IMHO. Its just bound to mess up sooner or later. Id rather A. find the problem and spend the money to fix it and get rid of the problem all together, or B. buy a tuner and just disable it completely.

Onemanzu · June 6th, 2007, 02:26 AM

extensions up front
mils out back...

thats how it goes

and also ... just sell the car if it doesn't work... ha jk...

OBS you can't get yours to work? you have long tubes catless mid and true's right?

did you ever get your build up done? i remember you were makin a vid... sorry off topic

your problem might be something else then if its not fixed... what was your code ?

One Bad Sixxx · June 6th, 2007, 04:01 AM

This was a long time ago, havent touched my car for about a year now. Im still kinda 5000 miles away from it. And no, the engine hasnt been bought yet. Its been, hm, postponed due to me being stupid with money. Again.

Its coming though.. Im not rushing it.

But anyway, back on topic. I really dont care about where the MILs and extensions go, the tuner was bought so Im gonna use that sucka to take off the damn light.

mmvi · June 6th, 2007, 06:03 PM

my car? 35k and I turned off my o2 sensors with the tuner.

Onemanzu · June 6th, 2007, 06:21 PM

and is it fixed now? or does it still wig out?

uhh if it still wigs out... turn them back on and look into MIL elims

mmvi · June 6th, 2007, 06:28 PM

it gave me the code, but, only after I unplug and replug my battery, then I erase the codes with my tuner, and they don't come back until I have to screw with the battery. the car runs fine with or without the sensors.

Onemanzu · June 6th, 2007, 06:31 PM

yea... i know but it runs better with the sensors... well it technically should run better unless you have a set tuned a.f ratio... then in that case... you don't technically need them

mmvi · June 6th, 2007, 06:35 PM

a.f?

Onemanzu · June 6th, 2007, 06:36 PM

air to fuel...

i meant to hit / but accidentally hit .

a/f

mmvi · June 6th, 2007, 06:38 PM

n/p i just dont understand why the light comes on ONLY after i do something with my battery, and not after i rease the codes. I only have to erase them once per resetting of the computer.

Onemanzu · June 6th, 2007, 06:44 PM

cuz the tuner has told the computer to fuckin forget the code and don't bother me with it ever again... but when you reset your comp it throughs out the command that it was given

mmvi · June 6th, 2007, 06:46 PM

I always thought that it just reset the computer for a while, and after so long the code came back. that's what I never understood.

GreenFaleen · June 6th, 2007, 08:05 PM

u got a flash tuner? tune the a/f ratio a bit leaner
