motor missing at high rpm HELP!?!?!

sounds like you have an ethanol problem.

Try and get a sample of the gas from the tank, put it in a clear container and see if you have little bubbles in the gas (little melted butter like substance).

If it is an ethanol problem and you put dry gas in there you could make the condition worse. I had an ethanol problem at the start of the year, drained 30 gallons (put it in my truck) and refilled the tank (+changed the fuel filter). Ran fine after that. Be careful of the additives, you're just adding more alcohol into your fuel system.
