Dear Sajeev,

Thank you for much good reading and practical knowledge for a very amateur do-it-yourselfer. My auto repair and maintenance skills are very limited, but I enjoy doing what I can myself. Even just the oil changes and having control of the materials used to perform it.

So you are looking for subjects, and here goes-this may resonate with any number of Miata owners. For about a year the CEL has been popping up a code (0126) that I read with a simple device purchased online that evidently means the engine is running too cold, which I have never even heard of, but why not? Insufficient combustion temp?
