today i installed a injen cold air intake and a weapon r header with the check engine light eliminator drove it around for 50 miles no CEL driving back from my girlfriends around 3 it threw a code. I did not reset the ecu or anything should i start with that? I was looking at another forum and they were saying that i may need another CEL eliminator. also the diagram weapon r sent to me showed the CEL eliminator was installed underneath the car but on the header there would be a hole..... I have the morning to fix it then wait till tuesday because most places r going to be closed monday. any one else have this issue with there install?
