kdm042 here again. An update on my Lexus RX300 situation: The problem I had with the engine idle was caused by a bad idle regulation valve. The valve failed finally, and my vehicle wouldn't stay started unless I kept my foot on the gas peddle. I had to get the vehicle towed to the dealer. I'll give the dealer credit: They had a loaner waiting for me, and my vehicle was back in my possession with the repair completed by 6 p.m. the day I turned it in. Which was, by the way, the day after the July 4th holiday.

I have over 92.000 miles on my 2002 RX 300, and have had only a few problems or mysterious occurances. 1. When the weather is cool (around 60 degrees), and the engine is cold, I sometimes cannot fill my gas tank above 3/4 full. This happened more often in January and February than any other month, and was more noticeable this year than last. Usually, I can fill the tank up all the way on the next trip to the gas station. 2. I've seen several posts about mysterious clicks and squeaks behind the dash. I've confirmed that the problem is with the AC fan by turning off the air flow. (I live in Louisiana, so I run the AC year round.) 3. In April, I was unable to get the vehicle started this afternoon. The service rep told me this has happened with other RX's, and it usually does not repeat. It hasn't. 4. Unfortunately, I got hit with a bigger problem on the interstate last night. My vehcile felt like the accelerator was trying to get stuck when I started decelerating. When I pulled off and put it in park, the engine started "rev"-ing like I was trying to gun it. (My foot was nowhere near the accelerator at the time.) When I started the vehicle this morning, the problem was still happening, so I took it to the dealer. They can't get the problem to repeat. They are keeping the RX overnight to try again in the morning. I understand that fixing any kind of intermittent problem is very difficult. If anyone has experienced anything similar, please post the cause and fix here. Thanks!
