I have 5500 miles with APR 91 oct program. Car runs great. Three days ago the CEL came on. I just took it to Jose at Euro Tech. He found an exceed upper limit code and cleared it. He said there was nothing more specific than that. I drove away and after one stop for lunch it came back on. So I gues it is off to the dealer...any ideas?
