stupid check engine light
 

ok i added this thing made my dc sports that extends my 02 sensor wire for when you do aftermarket exhaust...i added it and cleared the computer and the check engine light cam back on...so i checked it again and it said there was a circuit malfuntcion...what the hell am i supposed to do now???

did u solder the wires ? from what i've heard you are not supposed to solder them, just use electrical tape. make sure you don't have any shorts to the ground there
