Rough start and high Idle

Have the vehicle listed above Laredo all wheel drive.
Lately it has been starting real rough, and after doing so the rpm's soar up to 2 and a 1/2, and drives with a high idle. It literally eats up any amount of gas and the temperature gauge is some timey.
Rough meaning it sputters like there is no gas or it is flooded.
I also forgot to mention that as I accelerate the engine gives off a high pitched whine.
Any thoughts or suggestions would be greatly appreciated.
