LS400jockey

My cars ECU part number is 89661-50233. The dealer was able to reproduce the stall probem twice in 2 drives by letting a mechanic drive it home. He lives 60 miles from the dealer Their fix for the problem was to clean the throttle body and the IAC. So far this seems to have resolved the problem as he drove it home twice after the cleaning and the problem did not repeat. So far I have not driven it far enough to confirm it does not happen to me, I'll do that soon. Its now May I have not experience any of the symptoms since the service last November

My ls400 95 (144000 mile) is right now at the Lexus dealer with this issue, this is the second dealership that will be looking at it. The first did not fix it because they could not reproduce it. I drive it on the freeway every day. When I drive it for a distance greater than 30 minutes, speeds over 65, brake at a right turning off ramp, idle goes down and it stalls. The car immediately starts back up. Drives fine on the city streets, no more stalling after restarting the car. I get the "off throttle shock" as well. Thanks for giving me something to try.
