2001 Pontiac Grand Am

I have a 2001 grand am se and am having major problems. First of all my mileage is 123,000. All of my problems started 2 week ago when I noticed that the car felt like when I was accelerating the car was idling down and was pulling after it was switching gears (if that makes any sense to anyone!). I was told to check my transmission fluid and so I filled it up. About 3 days later the car started driving normal again. Now after 5 days its on to another problem. When I accelerate and take my foot off the gas the car does not slow down, it acts as if the cruise control is on and at times surges slightly. I also noticed that it is idling high sometimes at 2 when the car is in neutral. At this point I am not really sure what is wrong. Can anyone give me any insight to this headache? And, are the 2 problems possibly related to one another?Any help would be greatly appreciated!
