ok, so I have installed OBX headers a month go and i had a little trouble getting the EGR valve on but i finally got it on, there hasnt been any CEL light ever since i placed the EGR valve on the headers.. but now it comes on and off when im just driving around. I heard sometimes for other cars, when going full throttle, it can cause the CEL to light up, but i dont open the car up when i drive. I have no idea what the problem is.. I need help.. BIG TIME!.. any suggestions??

Thanks for your time!! (rei)
 
if the CEL came on after you installed the header its because you removed the stock header which houses a pre-cat. so essentially your second 02 sensor (before the mid-pipe) is reading that the airflow has changed since the cat is gone and is causing the CEL. it was inevitable so don't worry about it being something serious. there is a way around it. look up the non-fouler trick in the how-to section. by doing that it should get rid of the CEL.
