this model has what they call fly by wire.. no accelerator cable. If the computer detects a problem in the thottle system it will not allow the engine to accelerate and will show reduced power and possibly set a check engine light. The dealer usually wants to replace the throttle assembly which is very expensive and usually un nessesary.
I have had a lot of succes with just cleaning the throttle plates real good.

Hello, Check the wiring at the throttle body on the motor that drives the throttle plate. Wires can be broken inside the insulation or bad contact at the connector.
