If it's white, then they're most likely running C16 race gas or any equivelant. Seems like you've got the older version of the intake. Go buy some cams to help compensate you running rich  . Other than buying another intake of the revised family, you really have no other choice than to live with the light or hope that it doesn't come on. |
Wow... okay. I guess I'll call AEM and see if I can have it returned so they can send me a good one because when I called the AEM tech he said that the check engine light shouldn't come on. So I'll see. Thanks for the info. As for the cams... I heard that the cams already on the si are the best cams calibrated for that engine. So you could get cams but the ones on the engine are already the best you can get for the k20z3.
