Cellulose is wood fiber, how would ethanol turn into wood fiber in the injectors? Ethanol is typically used as an injector cleaner and, although it doesn't have the same energy per gram as gasoline, it burns quite well. It does have a "drying" effect on rubber gaskets and diaphragms, but I'm not following.
On another note I did notice a wire had pulled out of my o2 sensor. Going to see if it can be repaired, if not I'll have to replace a relatively new sensor and try to keep the wires better protected from now on. Will follow up once complete.
The ethanol used in gasoline is mostly made from corn. If that is a wood fibre - it's a new one on me. They don't use the husks - just the mushy kernals. To each his own.
