your idle must be a little low, adjust the screw on top of the throttle body under the rubber gromet and see if it helps

The problem is the fact that the MR2 is rejecting the automatic transmission much like a human body rejects a body part that is not its own.

The only solution is to remove the cancer and install a 5-speed.

Does the car have cruise control? If so, the problem could be related to that. I had a friend swap an automatic from a 93 with a 5 speed from a 95 and had very similar symptoms to what you described before they swapped the cruise control computers as well. I'm not sure if unplugging it will do the trick or not. What code is the computer giving?
