yea..i duno why..was drivin off the freeway n i noticed that another light turned on..the most dreaded light ever..

gonna take it to a diagnostic n see what codes are bein spit out..

any1 here in socal know of a place that is pretty cheap? the cheapest around here is like 40 bucks that i found before..just seein if any1 knows a cool place where i can get hookd up..better yet, maybe someone has a OBDII diagnostic tool themselves..

she ran fine on the way home n was nothing different..im thinking that perhaps the upper o2 sensor wires may be getting burnt..i found em just hanging in front of my headers (pretty close, almost rubbing) i dont know how it disconnectd from the fan housing, just happend while installng stuff i guess. gonna check the wiring in the morning n then check my spark plugs as well..gonna reset my ecu n all that good stuffs..n then imma take it in to get a diagnostic.

damn.

autozone is free to use their scanner

holy crap. thanks lew! never woulda thought.

code 27. sub oxygen sensor signal.

thats the precat o2 sensor rite? well, since i dont have one, i guess the CEL should come on (damn, i thot i was gonna be lucky)

is there any sort of problems that will arise because my exhaust system is lacking the 2nd o2 sensor? does it help with adjusting lean/rich A/F conditions?

thanks!

Next time just check the codes yourself

Your car needs 2 02 sensors to operate properly. not having the second one will throw a CEL.
