2000 Nissan Maxima transmission problems

We are currently waiting for a # 6 coil for our 2000 maxima, this part is on back order from the manufacturer and there are no available parts in the u.s. Since this part is on hold for other customers at other dealerships in the area, it seems to me that this part is failing on a lot of new cars(under three years old) this part should be recalled. We've also experienced a failure with the transmission and since our car was still under warranty at the time, we had it fixed at the manufacturers expense.

My car has steady idle rev up and down.when in drive, the engine race without moving and then suddenly take off.there is also a bucking effect when at speed between 35-45 miles per hour.
