ok so everything checked out good with the map sensor. but ever since i added the "myster oil" injection cleaner it hasnt sputtered at all. i ran the gas tank down to almost completely empty. so maybe the cleaner worked and maybe it didnt it might of been bad gas. i dont know but its running fine. so thanks to everyone who lended a helping hand. now on to fix all my leaks...oil pan, steering lines, water pump...and until the sputtering comes back.
