Purchased an '04 in mid 2005 with 30,000 mi on it. Just barely touch the accel pedal and the car would rocket from a dead stop. Horrible gas mileage. After 6 mos. the check engine light came on and the car became significantly slower and stopped downshifting when attempting to pass or speed up quickly. I know the two are connected somehow.. whats happening?

Hi, the next step is to have the diagnostic codes in the engine control module read out, these codes will help in the diagnosis of this problem.

I have a 2005 sorento and had same problem. The code read throttle position sensor. I went to the dealer (dealer only part) and bought one of the great price of $116 and it took care of the problem.
