#1 and #4 cylinder misfire, and a corresponding 'random' misfire code.
wtf? Code is cleared for a couple days now, but I noticed my mileage went to pot about 9 months after I bought the car (which corresponded to fall/winter in Canada). Need to get an oil change soon so I will talk to the dealship and see what they say about it. Hate paying for detailed diagnostics when I have an extended warranty which should cover that sort of crap.

Typically that is caused by spark plug or coil issues. My bet is fouled plugs from some bad gas.
