I would do a compression test. You could have a low cylinder. Also, those are the symptoms of using the Ethonal blend gas. Gas stations are using a blend called E10 which is 90% gasoline and 10% ethanol. Some gas stations are putting up big signs saying "No Ethanol" and sell pure gasoline. Ethanol can ruin all the seals on your engine, ruin your fuel system. Constantly clog your fuel filter. Symptoms of using ethanol are, Engine is hard to start, or fails to start, Engine sputters and misses, very poor fuel mileage. Also I always use B12 Chemtool in a can, you pour in the gas tank, works wonders for your fuel injectors.
Hope this helps any...
