You do realize you can get the error code read at a place like Autozone or Advanced Auto, right? That will eliminate some of the guess work.

Would definitely recommend investing in a Scangauge II.

CEL could be a range of things, get it READ then come back. And all modern cars (OBDII) come with 2 O2 sensors. Please help US before we can HELP YOU.

Without the code, my first guess would be a gas cap issue.

I concur sir. Especially if the CEL comes and goes. If there was something wrong with the O2, it would likely stay (unless it was a too rich/lean code, but that's unlikely on stock NA).

Anyone know where i can get good O2 cheaters?

i almost forgot how useless these forums are hahahah
first off im not an idiot i did take it somewhere to get scanned and thats what they concluded an o2 sensor. You guys are so busy bashing me that u forgot to read my question... i simply asked where i can get an o2 sensor for cheap... thats all

SquallLHeart

unless you did something to the car recently, there's no reason the O2 sensor would be a problem.

did you install or modify the car recently?

when i took it into the shop thats what the codes read. I have installed an intake and header but that was a while ago. The car has 55k on it

Online.

You never said for sure that it WAS an O2 sensor. Your exact quote was "I'm pretty sure its an O2 sensor". As a forum we can only take what you as the user input to form a conclusion. We we're simply trying to make sure you got the code read before throwing parts at a car.

anyone have any good sites, i found a few but they range around 150 and up

O'Reilly, Autozone, Advanced Auto, or TRDsparks.com

U said that u have a header on ur car. Do u have a cel eliminator??? Once u remove the cat the secondary 02 will read incorrectly and throw a code. If u dont, try that first for a cheap fix. U can make one urself by using 2 spark plug antifoulers and about 10 minutes of time to drill one of them out.
