I was driving on the highway today in my 09 FX50S, and suddenly my throttle stopped responding... The engine was still running and I could turn the car on and off several times but whenever I put it in gear my Rev counter wouldn't go over 1,100 Revs and the car would barely move if not stay still even... I put the car on a truck and took it home... Now after the car has been sitting for a few hours, it starts but turns off directly... My car has low mileage and I've never faced this problem before... That said, I have been out of town for two weeks and my car hasn't moved for that time, but I don't think that has anything to do with it... I'm going to take it to the dealership tomorrow to see if they can identify the problem but I thought I would try to see if anyone can help me here... Thanks in advance!
