This is a known issue with certain '03 and '04 MPV transmissions; my 2003 had the same problem. There is a Mazda technical service bulletin about this - 05-003/004 (Shift Shock). You need to take the van to a qualified shop and have them flash the transmission control module (TCM) with new firmware.
I had this done. It did not completely fix the problem but it did reduce its occurrence.

It sounds to like you my have a fuel delivery problem or timimg belt has slipped.(rubber belts stretchsometimes) I recommend the going to your local parts store and have run a diagnostic . If its the timimg the computer will give a code as well as a fuel code. This free to customers .

could be your torque convertor and if it is experiencing some chatter in the shifting then most likely you need to go to the transmission shop for a shift kit which is inexpensive.

SOURCE: The rpm fluctuates at idle
It could be several things...low fuel pressure, a lazy 0 2 sensor, and even an IAC. If there isn't any service engine lights coming on, you will need a qualified tech to do the test since a lazy 0 2 sensor has to be looked at with some type of a volts meter and a scanner has the capability of doing a better job yet since you wouldn't have to get underneath the vehicle. Don't be fooled into thinking that it is just one thing; it could be several depending on the mileage.
