went and had my codes scanned at autozone, hehe

[stevethepirate]

so my SES light has been on ever since i got my headers installed, but the car hasnt been driving right, so i wanted to check and make sure nothing else came up.

i walked into autozone and asked the lady if she could check it for me. she came out, plugged the thing in. after a minute or two, she just looked at me and said "wow! i hope you have a warranty on this car!" so i asked her what code it was throwing, at which point she told me there were 5. so i asked her which, and she said that it was my front and rear o2 sensors, and my catalytic converter. i just laughed, and said that it was good news. she got really weird, and told me that it was a serious problem... and was quite surprised when i told her that i caused it all, knowingly.

i just wanted to make sure it wasnt a misfire or something!


i know that my egr is part of the problem. so that is going to be fixed shortly. but what should i do for the others? is my best bet to get some o2 sims? have it tuned? anything else?

When I had my headers installed the shop told me that its common for O2 sensors to go bad afterwards. Replace the O2 sensors and you should be fine. I had to replace mine after 500 miles with the new headers.

get the o2 sim. i had the same problem. 3 mins of work and it was fine

do i need an o2 sim for every sensor? or is it just one?

Re: went and had my codes scanned at autozone, hehe

isn't it supposed to be the 2 upper o2s? I know on my car those were the only sensors that were *****ing, i wired in the sims and that was it. if you know someone with hp tuners they can go in and just turn it off that way to.

I think they only make a sim for the after cat sensor. I've had my headers on now for about 5k miles and haven't thrown a code. I have heard of them going bad, should it throw a code if they are bad or should i just replace them?

Yea, my 02's went bad after I installed my headers as well. I replaced them and it threw the code again. I just had the codes tuned out and my 02 system turned off with the tune. No problems has resulted because of that.

what could cause the front o2's to go bad?

The sim is for the post-cat sensor.

The sim is for the post-cat sensor.

yep, i wouldnt put them on the front 2, their alot more important.

usaully just the post cat 02 sensor throws a code from what i understand. mine only threw ( still throwing ) one for the post cat.

btw, 02 sims are hit and miss, i have one and it worked for a month or so, then the light came back on. other people have this problem too, just have to tune it out or live with it i guess.

Holy **** i can not believe what I am reading. the post cat 02 sensor is the only sensor that doesn't really matter and get be tuned out or simmed. the front two are extremely important to engine drive-ability.

Re: went and had my codes scanned at autozone, hehe

i know that the front 2 are more important. what could be causing them though??
the egr?
