Hello and welcome to JustAnswer!

You most likely have an electronic throttle control related issue. Possible causes would be the throttle body, accelerator pedal position sensor, throttle position sensor, wiring, an actual or perceived intake restriction or vacuum leak. It will take some testing to determine exactly what is going on.

The first step in diagnosing the problem is to use a scan tool or code reader to see what fault codes are setting and then testing can be done from there. Do you know what codes are setting?
