I have been having this problem for a little while now. The car drives great but when I am coming to a stop the rpms drop to 500 the car shakes a bit and the car seems like it is going to stall but then when I come to a complete stop the rpms raise back to normal. This happens more often when I am coming to a stop from high speeds.

I just changed the ignition wires, sparkplus, dist cap and rotor and nothing has changed but the car runs even better now. Does anyone have any idea what this could be.

Thanks
