I just installed the perrin cel fix, the one you splice, the cel went off within about 10 miles. I know it's installed correctly, I really want to run a test pipe but I don't want a cel. Has anyone else had this problem with the perrin cel fix, if so what did you do?
thanks for your help

 

I heard you may have to space out the O2 sensor with a washer. Do a search, I know I read that here.
