Well, first off, I dare to notice, that the expression "to be going to" is not exactly the conversational equivalent of the "will". There are some shades of the meanings, I believe. Classically speaking, we use "to be going to" if we are not quite certain about our own intentions and plans. The "will" sounds more determined, more adamant. More formal, I'd say. (So, yes, less conversational as well.)
But, generally speaking.... The Doninphxaz says, they often talk like that in the USA... Perhaps, in the area where he lives, yes, I easily believe this. Because one of the amazing specialties of the USA is that people speak completely differently in diferent places. The Californians may have trouble to understand Texans; people from North Carolina don't use the same words as people from Oregon.... Say, only Southerners say "I reckon I'm fixin' to go." Or, "Y'all alright here?" The words usage around the USA varies, this is my point.
As far as the expression "I am going to go" is concerned, I agree, there is nothing wrong with it, gramatically, but I, personally, would avoid it. It's just sound awkward, guys, can you not hear that???
