Answers :

Probably water in the gas..., although its not common.. ... this problem should cure itself with your next tank of gas.. its not likely to be anything else..is your check engine light on?? have you refilled the tank with gas yet?
\012Injector cleaner is ok, however they make a gasline product for up north to evaporate water out of the gas tank because the water will create ice or slush in the tank in cold weather..
\012Methyl Cloride is what I used to use in Canada, in the winter to evaporate water out of the tank.
\012And maybe you have a lot of water in the tank.... when you take off the fuel filter, you will be able to see water beading up (a clear gasline hose which does not come with your car) will tell you all sorts of stories about water and how clean your gas is (on the gas tank side of your filter)...
