Spare tire donut messing with the ATTS?
I've been riding around with the donut on the front for a few weeks waiting to get new wheels in a week or so 'cause I cracked one of the stockies. Today my ATTS / Check engine light came on. I know they always come on together, but I just changed my cat and seconary O2 sensor. Could the spare up front cause the ATTS to malfunction?
