Hey once again another issue

, this time whenever i start the car the RPMs get low and it just runs rough and will cut off, even when i hit the gas it doesn't want to do anything. But I read this
Filter Problems
A completely plugged fuel filter will stop your engine cold by choking off the flow of fuel to the carburetor or injectors. The engine may not start, or it may start, then stall and die.
thats exactly whats happening to my car it starts, sputters, and will die. i changed the spark plugs but it still does it.
HELP MEE
