Hey all!!! So I went and picked up an 07 quad cab 4x4 w/ the auto and it is awesome!!!. I can't believe I ever drove a gasser. This forum is awesome but I have a question. Is there anywhere on here a noob can get a good understanding of what you gurus are talking about!!!???? What maint do I need to perform?? What is a CEL code? I have searched around and can only find bits a pieces. Are there any threads anyone knows about that explains some of these things??? It took me 2 days to figure out what and where the DPF was:banghead:. Any help appreciated.
