I started our RX300 to pull it into the garage to change the oil. It died when I put it into reverse and then wouldn't start unless I kept my foot on the gas. I changed the oil, same symptom. One Bing search and I found this post. After a trip to the store for a larger screw driver, some cleaner and then a couple of hours under the hood and bingo, we are back in business.
Thanks!!!
