Gas/Fuel quality
so i just moved from Virginia to Maine. about 2 tanks before i moved i changed the plugs fuel filter and cleaned k&n. ever since i got to virginia (from Texas) it always started funky, it would kind of stumble up. it ran fine it would just stumble right at start up. i always kept up with maintenance and never understood why it did this.
so when i got to maine i would say the second full tank i filled up with it began to start normal again, and has ever since. the only thing i can think of is difference in gas. its a 5.4 by the way. maybe air quality too???
what do you guys think? anyone ever experienced the same problem?

You may have something there...
Don't you remember last year, or was it the year before (for that matter, seems like something happens almost every year), that a pipeline went down or a refinery had problems? The @%$#!&% tree huggers were all upset because the wrong blends of gasoline were being sent to some areas of the country. Seems we have several DOZEN "designer blends" of gasoline used in different perts of the country for various reasons, but mostly smog or ozone.
And then some states, cities, or regions think they're real smart and decide they need E-10 in all the pumps (but unlabelled so folks can't complain whenthere are problems).
Wouldn't you thing the term gasoline would be one stable, consistent product?
A McDonald's Big Mac is more consistent, nationwide, than our motor fuel is.
Wouldn't you think if there are local problems they would deal with them using a local measure? Like if there are too many vehicles downtown, build suburban parking lots, provide mass transit, and see to it that all parking is so exorbitantly high that even Donald Trump would raise his eyebrows at the cost. But no, folks like to crap in their nest and expect the rest of the tree to bail them out of their mess.
YES, THE GASOLINE IS LIKELY DIFFERENT IN MAINE.

It has been my experience that the 5.4L V-8 is sensitive to the perentage of ethanol in the gasoline. I notice a big difference in fuel consumption/power when using a 10% ethanol blend. Fuel mileage and power seem to go down.

I don't know that there is an additive that will counteract the ethanol. The ethanol brings additional oxygen to the combustion process (oxygenates gasoline). MBTE used to do this, but they decided it was bad stuff and it can no longer be used. The additional oxygen, plus the fact that ethanol doesn't have as many BTUs as gasoline, means you have to burn a little more to get the same power.
I tried running a higher octane (90) since it was the same price as the 87 octane fuel, but there seemed to be no difference.

IAC = Idle Air Circuit or Control. It is located in the back of the engine compartment on top of the engine. If you do a search there are several posts and pictures with explanation on how to clean it or replace it. I Never use any gas with ethanol in it. The ethanol is known for causing many problemssuch as rotted fuel lines and eating rubber.

Hey 995.4SD, where abouts in Maine? I retired from the Air Force up there!
To answer your question, Maine (well, actually all of New England) use a blended fuel to meet local pollution restrictions. You'll notice a slight difference when the migrate to and from the winter blend. When I transferred from TX to Philly, I didn't notice any differences but when I went from Philly to Maine I did....and that's how it was explained to me so we just pressed on.
