just had a great example of the effect of ethanol on idle (and probably other things!). I had run several tanks of ethanol free gas while adjusting the ECU fuel mixture knob. Had the idle running extremely well and very stable. Filled up with normal gas a couple of days ago and with only half a tank used my idle dropped and got very choppy. Enriched the mixture at the ECU (clockwise turn) a few clicks now running smooth again. Soooo...ethanol equals a lean burn and non ethanol equals rich burn...just say'n!
