Could be a variety of things. Is the Check Engine Light on, and are there 
any ECU codes being output?

Your fuel-air mixture is way off. Possibilities:
1. leaking injector is dribbling fuel all the time.
2. Dirty air cleaner.
3. Timing is off.
4. O2 sensor slow or failed
5. clogged Catalytic converter.
6. coolant temp sensor disconnected or failed. This signals the ECU to 
adjust the timing and mixture.
7. partial ECU failure (always in open-loop mode)
8. Assuming an automatic, is it changing gear correctly? eg to 4th OD, not

stuck in 2nd gear Limp mode.


You could try
a) disconnecting the battery for 30 seconds to reset the ECU
b) look for any vacuum hose air leaks (unlikely, this usually causes the
car 
to run lean and hot)
c) put some injector cleaner in the gas

d) take it to the dealer for a tune up. Is it still under warranty?
