    so i put in 110 leaded at the track, would this lie under fuel contamination?
    I had this come on once before and i reset it, and it didnt come on until i put leaded gas in it again.

    You may have lead fouled your O2 sensors. Thsi is easy to do especially if they are older and have mileage on them. NGK makes a Lead resistant O2 sensor you might want to look into.
    After some time of driving with 93, the lead will eventually blow out of the pores of the sensor, it took mine 250 miles once for it to turn off the SES light. Then I replaced them with new sensors. Be aware of using Bosch O2's, they are junk. I recommend NGK or Standard. FYI, running more than 20% 110 octane (2gal to 10gal) is overkill, unless you are highly modified. -Tim
