I have a 94 Millenia S. I live in New Zealand. The car runs very well except that it has become very sluggish when accelerating from a standing start on a hill (or if under a load). The supercharger will also surge if under reasonable acceleration rather than increase in speed smoothly.The gearbox is O.K. Mazda Service in New Zealand have done a computer fault readout on the car and as a result have replaced a solonoid connected to the supercharger. However, this has not rectified the problem. Has anyone experienced a similar problem and can provide a solution?. Thanks. Dean
