Hey, I normally post on G35driver since I have a 2003 G35 coupe. However, since there are more of you here with forced induction, I have a question for you. It's been about 3 weeks since my Greddy TT kit was installed along with the FMIC and exhaust. Two days ago the "Service Engine Soon" light came on and it has been on ever since. I am assuming that it is just an emissions thing ( I still have my cats in though), but I do not have an OBDII scanner to verify this. Has anyone else had this happenor have any idea what is causing this?
