The Monday before this one (before I fell ill) I discovered a Check Engine Light lighting up my life. I went to AutoZone to see what the code was – “Low Emmisions leak – very small.” This is apparently the infamous Mazda6 “loose gas cap” code – so I decided not to do anything about it until my next oil change/service (in a few weeks). Yesterday – the CEL vanished.
Good thing too – it was bugging me that I was going to drive to San Diego today with a CEL (“very small” or not).
