hey all hooked up an a/f gauge to my car today and its just staying lit in the rich position even after i took the car and drove it on the interstate it didnt move at all well the question is does it matter which o2 sensor its hooked to? i wired it in the front o2 sensor on the drivers side or maybe my car is just running rich lol...i dont get carbon or anything but the exhaust is a lil teary eyes sometimes thanks

[HMUSN]

O/R exhaust?

and you really should invest in a wide band instead of the narrow band you have.

[jasons_98gt]

yea its saying the exhaust is rich but im not getting black smoke or anything

[HMUSN]

I'm asking if you have Off Road Exhaust.

[jasons_98gt]

oh sorry...no i have the stock exhaust

[HMUSN]

exhaust doesn't get rich. an engine's a/f mixture is what gets rich/lean.
to be honest with you the narrow band sensor you have is a pos and nothing but a fancy light show. as far as your running rich issue run a can of seafoam through it and see if that clears it up.

[jasons_98gt]

yea i ran seafoam through it friday when i took a trip for the weekend went about 200 miles back and forth im guessing it might just be time for some new 02 sensors? after all they are original and have almost 150k on them

[HMUSN]

change em out. can't hurt.

( get a wide band) <-- listen

it's a MUST

[jasons_98gt]

lol i was lookin at wideband ones they are a lil to expensive for my liking especially since im trying to save for a p.i upgrade but thanks alot man

[HMUSN]

ok. just so you know man.. wide band > narrow band.

a narrow band can't read properly when you go wide open throttle so if you plan on modding your car more please invest in one for your own good.

im just wondering if i hooked it up to the wrong o2 wire lol cause when i turn the key to the run position engine not running the rich light is already on?? i tapped into the red wire does this help any

[jasons_98gt]

any help hm?

[HMUSN]

you mean your coolant light I assume.
check your coolant level.

[jasons_98gt]

no not the coolant light i have a haynes book and got the info out of that for the signal wire so i looked at the connector and on the driver side the red wire was supposedly the signal wire so i tapped into that.....as i was just looking at the directions it said there shouldnt be anything lit with the key in run position and motor off well the rich light is on with k/on engine off

[HMUSN]

you don't have a "running rich light" got a pic?

[jasons_98gt]

i mean the rich light on the gauge is on before the engine is started no pics sorry just installed it today

[HMUSN]

well of course it is.

the gauge isn't reading anything

[jasons_98gt]

yea so does that mean i hooked it to the wrong o2 wire?

[HMUSN]

no. it means your cars not started so the gauge isn't reading anything.

[jasons_98gt]

right right haha i feel like a horses ass but according to the instructions no light should be on the gauge with the motor off
