P0139 Error Code 05 Civic after header
Hello, After an install of an OBX header in my 05 honda divic dx/vp I recieve error code P0139 (secondary 02 sensor slow to respond). Now on the 05 dx/vp the cat is buit into the header. So of course on my OBX header there is no cat. So, I have purchased 2 different MIL eliminators from 2 seperate companies and still receive this same error code. Can any help me on this or have any ideas?
Thanks for your time
