I just installed a juice box on my 08 premiere and the check engine light keeps coming on. I already installed one on my RS no problem, works great. I have taken the breather cover off, installled to the inj. ports twice, ground is good, and O2 Sensor is connected properly. Just wondering if i'm the only one having this problem or is it specific to just the 08? Does anyone have a fix for my serious issue so that I havent wasted $235.00. Thanks to all!!!!
