your fuel lines could be bad or cluttered. Fuel filter might be very dirty and not cleaning the fuel like its soppoesd to, so you get more particles into the mixture. Or what i think is the problem is, you have a dirty or corroded fuel injector. If its dirty or corroded, the fuel spray will not be even, which can result in not properly igniting the fuel, and messing up your cars fuel/air mixture.
 
I have a problem with my car. When ever i put gas in it it starts sputtering for a little bit until it burns some gas then it runs normal. Also i have noticed that if i leave it parked for too long especially like on a hill it also sputter for a little bit. In the morning when i start so it warms up it starts up just fine but then i go outside to leave for work and its off.. the car dies....

what can it be... i know its not the fuel pump, fuel filter, spark plugs or wire because i already change all of those things.....

some people have told me that the fuel lines may be dirty or that its a sensor

i really dont know what to do is driving me crazy
 
Check your fuel pressure regulator. Also, locate and clean out thoroughly your throttle body and plate, and especially, the idle air control valve. Clean your PCV and hose, as well. Idle is affected by these factors, mostly. If the throttle body does not return to rest setting, it will signal the computer to spray too much gas, causing stutter and exhaust system meltdown. I hope you are using Bosch Platinum or Nippondenso Iridium plugs!!!
 
If you're certain its not the fuel pump,filter,plugs etc, then the problem could be with the fuel injector(dirty) or the fuel itself. Try putting in a few bottles of fuel system cleaner(STP or shell V-power) as well as try putting shell V-power for a couple of tanks. These have a lot of additives in them which will clean up the entire fuel injection System right from the tank to the injectors and see if the situation improves. If it was a sensor issue then youre check engine light would be on. If that is the case get a diagnosis for that.
