Hey guys, i recently got a set of OBX 4-1 headers, so i installed them. First time around i completely forgot the defowler fix, so i threw a CEL. i then took the spark plug defouler, drilled the 1 inch hole, and installed it. Reset the code with my OBD2 scanner and the CEL came back. Thought maybe i had to reset the ECU so i left the battery unplugged over night, drove the car for 150km and the CEL came back on again. Am i doing something wrong here?
Thanks
Joey
