Wideband afr off after race gas
I went to the track last weekend and put about 4 gallons of Cam 2 110 octane leaded race gas w/ 6-7 gallons of 93 pump. Now my AEM wideband is reading 13.9 when cruising. Did the leaded fuel mess up the wideband 02 sensor or is something else the problem. Before it always read 14.9 ish when cruising. I need to know if the leaded gas could mess up the o2 sensors or if it just needs to be recalibrated. I thought that the manual for the AEM said that you could recalibrate it somehow.
