Started my 2008 Toyota 4runner. Never touched the accelerator pedal. Engine raced uncontrollably to around 7-8000 rpm and shuddered terribly. Immediately turned the engine off and then tried it again. Did same thing. Took vehicle to the dealership where they said they couldn't duplicate the symptoms and said there weren't any codes stored in the computer. Was told they would call Toyota technical to report issue. Never have been contacted. This incident only reinforces the belief that Toyota has issues other than the "recall fix". I believe that it is an electrical/computer problem. It should be noted that my vehicle is not even on the recall list.
