Ok, i know this is probably a long shot....but i hope someone can help

currently i have 34,000 miles on my car. Today while I was driving, "service engine soon" light came on. Can someone tell me what might be the cause of this?

I have frankencar intake and custom catback.

Thank you very much

 

EDIT: click BACK, click 4th generation... Look up.... see FAQ...











cmon, you musta learned that by now

 

Sounds like a o2 sensor

 

that's what i was thinking too, since I only had the catback for a week.

is it possible to replace O2 sensor yourself? or do i have to do it at the dealer?

and will it become a major problem if I can't get it fix until next weekend?

thanks

 

Gimmie an "F"!
Gimmie an "A"!
Gimmie a "Q"!
What does that spell?

You have a lot of catching up to do!

 

would you guys just SHUT THE FUXK UP already. I'm reading through old posts at the same time right now. I just wanted to see what other people think OK?

 

If you check the code you could know for sure, but on my 4th gen the f***** EVAP cann vent ctr. caused the light to turn on. I would reset the ECU at first, and it would be good for about 1k, but now if I reset it, it comes back immediately. I followed the web instructions on how to clean it out, but sorry, NO GO. Time to let Nissan fix it, those mo** thieves. At least I got a 20% parts/labor, so the more they rob me, the more I save.

With such low mileage, I'd reset the ECU and see if/how long it takes for the light to come back.

 

lol, this is gonna sound embarrassing. I just check the gas cap.....that shiat was even on there.

 

hahahahaha

 

it could be anything, you just cant guess what it is... read the code then you will know.

 

i meant the gas cap WASN'T even on there
the light went off today

 

you are a genius

 

true

 

yeah this will do it

It should shut itslef off in a little while.
