So my emissions light (orange one that has a picture of an engine with the word check in it) came on this morning out of no where...

i checked my manual and it says it could be just because my gasoline cap isn't on tight enough so I tightened it... it didn't work.

only thing I have done to my car is an aem cai. I haven't cleaned it in about a year so I thought that might be screwing with my emissions scensors. I'm waiting for it to dry right now and then I'll reset my ecu and see if the light turns off..

sooo.... assuming that the light doesn't turn off, what could it be?

 

well you'll have to check the code.
