Does anyone know where I can get a CEL code pulled for free? I am pretty sure it's my O2 Sensor set off by my Borla Header but I want to know for sure. I there any other way I can know that it is the O2 sensor? Like maybe taking it out for a while or something like that? Thanks.

 

Go to Checker or Autozone, and tell them you're interested in buying an OBII diagnostic scanner, but u want to test it out first. I did this probably a dozen times before I bought one!!
