Could be several things... O2 Sensor, fuel issue etc. Most of the time you will find that it's simply the car's computer needs to be reset (due to dead battery or having the battery unhooked for a few minutes.
Heres a quick way to reset the car's computer;
make sure the car is warmed up
pop the hood and unhook the negative battery terminal
make sure that the terminals are not corroded, if so you need to clean them first (i use baking soda and water but most just use a wire brush)
with the negative unhooked, get in your car and press the brake pedal and hold for about a minute
get back out of the car and reconnect the negative terminal
start the car and let it idle for about 5 minutes
Drive the car around. be easy on it at first, because the car will sputter a little bit more than likely. The car is resetting several things, like the airflow detection etc.
If that doesnt help, then you probably need to try cleaing out the Mass Airflow Sensor (MAF)
Google that
there is actually no problem. it sputters because the engine has to start up and it may be the way you place the key inside the ignition. so don't worry because it isn't a big problem
I had the same problem with a jeep wrangler and I replaced the throttle position sensor and that solved my problem.
It could be the fuel pump.
I am assuming this is a problem on a high mileage car? It most likely is a problem with the carburetor. The carborator is likely dirty, so take it out and give it a good cleaning with a toothbrush. But due to the lack of details i have no idea what the problem really is
Time to get a new car!
That is called "run on." It is usually caused by the ignition timing being too far advanced. If it is an automatic, shut it off in gear, until you get the problem fixed.
Take it to Auto Zone and have the codes read for free.
It depends on how long the car stays running for. If it turns over and then shuts down after a few seconds and sputters it could be a fuel filter. If the car runs for a few mins and then dies out it could be a computer problem. The ECM might be starting to go.
It seems as if there may be a problem with your car getting enough power of enough fuel while coming out of a turn. The best way to find out for sure would be to take your car to the mechanic for diagnostic testing.
need to check your evap system or you have a blown head
If a car sputters when it accelerates there may be a problem with the ignition. Another option is that the timing belt is malfunctioning.
Your alternator is not keeping the battery charged.
