Just got done installing my brand new Posi ported Dragon TB and plenum on the 03' while I was at it I went ahead and installed my new JLT Cold Air intake. Went by the instructions that came with it, one part that was with it that the instructions never mentioned was a black circle piece with a hole in the middle and 5 screws that went around it so we just didn't install it because we couldn't figure out where it would go. After we got done we tried starting it up to make sure it idles right. It will turn over but die instantly. What is the problem? We checked all the connections and everything is connected. Kind of at a halt on what to do. Thanks!!!
