2007 Ford Edge "sputters"

I noticed this a while back and has been getting a little worse it seems over time. The Edge while driving will sputter violently when given a slight amount of gas as to remain at a certain speed. If I give it a little more gas it clears up and drives just fine. That problem has not gotten worse or changed, what has gotten worse is on the highway with cruise activated it will do a slight sputter periodically on flat and hilly roads. Absolutely no warning lights are on and have never been on. I cleaned the MAF sensor and replaced the air filter, though the MAF sensor was slightly different looking from the others I have seen. I hate to take it to a shop that is just going to throw parts in it with no codes being shown just hopeing to make a quick buck off me. The problem started I would say around 100000 miles and im at 109000 now.
