Has there been accidents caused by surging engines or stuck acceleration

The most likely cause of an accelerator pedal sticking is a format that has been lodged in the way of the accelerator pedal. It is possible although highly unlikely that the throttle would stick for some reason. There is a throttle cable and throttle body, and the engine idle base speed is influenced by metered air and fuel delivery ratios. Testing would have to be performed. I can tell you in the field that it's not something we see happen -- every car has it's own history and possible issues, and only hands on testing can reveal what happened. Good luck.
