So my car sat with a quarter tank of e85 for about 5weeks after replacing the alternator I drove to the station about 6 miles from my house and filled her up with fresh corn. As soon as I started the car it smoked. After running pretty hard for the night it was still smoking especially bad with no load revs. Any idea what's going on? I'm gonna pull the plugs and possable drain the tank. It also Dosent smell like it used to.
