I was driving at about 60 mph and suddenly I felt the vehicle have some type of loss of power. I tried to press on the gas pedal and the car would not accelerate and the rpm odometer was "jumping" from 1 to 1. 5 and the idle was horribly rough. The motor sounded like it was a forced idle. I pulled to the side of the road and opened the hood to see what was going on, I checked everything to see if maybe there was anything loose or something in there and there was nothing nothing that I could see spot on or notice spot on. I did some research on the 'symptoms" and cleaning or forcing shut the throttle actuator was the number one thing that kept showing. So I pulled everything apart and cleaned it and sprayed some wd-40. Once I out everything back together I then started the vehicle and the wrench light turned off and it was running like normal.
