O2 Sensor

Metallman56 · 08-04-2006, 07:33 AM

this is really starting to grind my gears. my check engine light has been on for a while now. about a year ago when i put on my TOG headers, is about the time the light came on. scanner said O2 sensor before the cat. so needless to say i replaced it. the light came on again about a week later. same code. at this point i thought maybe the wire extension had touched the headers and maybe burned through. there was a place on it that the black plastic tube around the 4 wires melted, but none of the wires were exposed. i figured who cares, i'll just replace it. i did so, and made sure it was not anywhere near the headers. the light did not go off. so i finally decided to spend $90 and get a new O2. took it right over to autozone, they reset the code, and about 5 miles later the light was back on. took it back to AZ they told me it was the o2 before the cat. so now i dont know what to do. it doesnt make sense. wouldnt my gas millage be bad if my o2 was bad? last weekend going 70 mph, i was getting 35 mpg. i'm stumped. no clue. the light is not only anoying being on all the time, but if anther one of the 120 sensors f*ck up, then i wont know about it. anyone any suggestions?

Pre-cat O2 sensor, what problems would this cause?

Hahaha we are so on the same boat.

Metallman56 · 08-04-2006, 08:34 AM

well that was more informative then the last link. ok, let me also say that my car runs fine. the only thing it has been doing, and only like once a week, is hesitate at about 1500 rpms. but if i get into the gas it stops. and its only on a cold engine. i dont know if that related. so a pcm short? interesting. ok so 2 more questions. would a pcm programmer fix this, and if not, i am going to have to get a new pcm arnt i?

coupe · 08-04-2006, 08:45 AM

I really dont think its PCM related, so hard to believe it would be.
I have the same exact problems you do though.

Metallman56 · 08-04-2006, 08:51 AM

maybe that would explain my high QM times. my light was on when i ran. do you think it could be?

coupe · 08-04-2006, 08:54 AM

I ran when my light was on but at that time there where no symptoms that i have now, i still ran 4 14.9's.

Metallman56 · 08-04-2006, 08:59 AM

hmmmm, well that sucks, for me. i just dont have any clue how to turn the d*mn light off. so far i have waisted about $150 and 3-4 hours. i am about ready to take it to my mechanic and tell him i dont care what he has to do, turn the light off.

coupe · 08-04-2006, 09:22 AM

Im about at that point also. Just dont know what else to do. At least i know a good mechanic who loves my car. Im gonna grant him his wish and let him tinker with it. I really dont want to do that though.

Metallman56 · 08-04-2006, 09:27 AM

i know what you mean. i think were just out of options. also i dont want my mechanic to buy a new o2 for it, cause my o2 should be fine. its less then 2 weeks old. and i hate being without my car.

coupe · 08-04-2006, 09:35 AM

Yup mine is only 2 weeks old and has MAYBE 100 miles on it.....more like 60 miles

.
Im taking it to AZ after work to get the codes read again.

Metallman56 · 08-04-2006, 09:50 AM

lets keep each other updated on this.

coupe · 08-04-2006, 10:45 AM

No problem man.
I just went to lunch and it didnt act up at all but i bet when i go home its gonna act up on me.

Metallman56 · 08-04-2006, 11:17 AM

, looks like we have the same luck too.

coupe · 08-04-2006, 11:24 AM

Im starting to think its the color red

Metallman56 · 08-04-2006, 12:39 PM

hey, if this is the only problem i have with mine, i'l be happy

coupe · 08-04-2006, 12:56 PM

I feel ya on that for sure.

Sprucegagt · 08-04-2006, 01:48 PM

What is the actual trouble code.

coupe · 08-04-2006, 05:55 PM

Im goin to AZ tomorrow, didnt have time today. I will post the code when i get it.

Metallman56 · 08-07-2006, 01:36 PM

coupe · 08-07-2006, 04:08 PM
