After putting in $20.00 worth of E85 (85% ethanol, 15% gasoline) shortly there after my "check engine light" came on. I have NO other problems, oil pressure is same, oil level is same, not over heating, alternator still working .... as a matter of fact I think it idles smoother now. But will the light go out if I revert back to gasoline ..... will the E85 harm anything? should I drain it, or run it out? Does anything need to be reset?
Thanks Everyone! Merry Christmas AND a Happy New Year to all!
