I would be interested in hearing from folks who have replaced their Throttle Position Sensors with a description of what symptoms the replacement fixed. I would prefer to hear from these folks first, prior to opening the topic up to broadband speculation as to solutions to my problem.
The problem - I have had a very intermittent stalling problem at idle (or just coming off of idle) beginning at ~ 9000 miles on my '03 FJR. Now with 37,000 miles on the clock, it is occurring more frequently (3 times in 200 miles yesterday), but still difficult to reproduce on demand. "Occasionally" when I have been in slow-moving, stop-and-go traffic (with the engine temp at two bars), as I gradually give the FJR throttle at idle (1000 - 1100 RPM) the RPM will decrease to about 600 RPM and stall. I was able to reproduce it at my dealer today, after about 10 minutes of trying. My suspicion is that when the Throttle Position Sensor gets hot, there is a fine spot in the rheostat where there is an open circuit (or other abnormal resistance) that confuses the EFI computer and sends the wrong mixture.
