Posted back in September? how the check engine light would randomly go on and off and it continued doing it until about 3 weeks back where it hasn't come back on. Today, I decided to finally take it for an emissions test and no stored codes were found :-)
I did start putting mid grade gas in it, so if that "cured it" or just an onset of cooler weather (seemed to happen more often in hot weather) was the reason for no more check engine light lately I have no idea. I'll switch back to the low grade and see if it returns. The longest it ever stayed on was about an hour and sometimes it would come on 2 -3 times a week or just once a month (like I said, random). Gas mileage never seemed to suffer(alas, almost all city driving and red lights every few blocks) so I never really did check into it further.
