My pride and joy has developed a weird noise. Just touching throttle pedal results in a light 'creaking' noise. Itdoesn't happen when the engine OFF so I guess it is not simply mechanical. .....and it doesn't happen with the ignition ON and engine OFF. I only hear it when the engine is running and I lightly touch the pedal. The car is working fine - no other problems. Anybody encountered this before?
