Need to know what codes are in the vehicle. Goto your local parts store and get it checked or buy a inexpensive blue tooth scanner and let us know what codes are in the vehicle. We can help more after that.

 Gas pedal and throttlebody most common issues. 

 

 Need to read the codes and find out where to start looking. 

 

 Also inspect the wiring at the throttlebody. 

 

  All of the above checks out you may have a bad PCM.  I've never seen a case of a bad PCM until last week  but there's a first for everything .
