Hello, I have changed my engine assembly and gearbox of my Storia/Duet 99 but still I have a problem. When I shift it to any gear except P and N, the RPM falls down and the engine start vibration as if the foundation is broken. I checked each and everything but unable to trace the problem. The auto chock also works sometimes, I went to few electritions, they run a diagnostic test over it but still unable to solve. Will somebody kindly tell me any good machenic or electrition for Storia/Duet in Peshawar or Rawalpindi/Islamabad. Will be really thankful.
