i dunno, try unplugging the battery for a few minutes then see if it comes back on.

 

its prolly your intake i had the same problem

 

did you click it too many times, a new gas cap might be needed

 

I clicked it twice, and still no luck... but im gonna try disconneting the battery and see if that works.

EDIT: I dont have any tools

 

Go to your local auto parts store and see if they'll pull the code for you, then have someone here look it up. Or you could just buy a code reader (I'm thinking about doing this) they only cost around $40.

 

I'd say battery too.

 

remember it still could be the 02 sensor also

 

Unplugging the battery probably won't, or shouldn't clear the code. OBD-ll cars store the codes in memory. I believe autozone checks codes for free.

 

my light went on because i put 91 gas instead of 87

 

if it is an o2 sensor problem, removing battery will allow it to shut off till the car runs long enough to throw a new signal. Normaly under 30 mins and you should have this. When I had injector "issues", I couldn't get the car off my driveway without the light coming one after a reset. Anyhow, good luck.

 

i reset the ecu (unplug battery) and it came off. Drove around for 15mins and hasnt came on since, so ill just keep an eye on it... if it comes on, ill head to autozone.

 

UPDATE.

it came on again (dammit), so I headed to autozone about 15mins ago. Hooked up the odb II scanner and it came back "link error". I need an odb III scanner. Dammit, now I gotta take parts off my car, so mitsu can look @ it

 

did u turn the key on??? i used the autozone one when i didnt have a cat and my light came on. u have to turn the key on... the obd2 is gonna work.

 

^^^ i just went about 10mins ago, it came back as P0171 - System To Lean (Bank1)

Now what?

 

too lean?.....check your plugs, when mine threw a lean code it also thres a misfire code at the same time. so check the plugs
