#15 of 20 Re: 2001 Lexus RX300 vibration [wwest] by sostabarak Dec 31, 2008 (2:23 pm)
Replying to: wwest (Dec 16, 2008 10:53 am) Problem solved. Fortunately it had nothing to do with the transmission. Idle air control valve is what the problem was. Lexus is offering to pay half as it is now out of warranty but was originally reported while still under warranty. Wish me luck on arguing for the other half. Thanks for all the input.

Replying to: sostabarak (Dec 31, 2008 2:23 pm) As a general rule all that is needed for correcting an idle air control valve problem is cleaning the (smallish) air bypass port/channel. Clean the port/channel/orifice, unplug the battery so the engine ECU is forced to "relearn" the PWM setting for the valve's control solenoid, and be on your way.   The Lexus service shop should know this. You may be getting a "refurbished" control valve removed from some previous "service" and then cleaned in preparation for "cleaning" the next victims pockets.   If, sometime in the past, you have used, experimented with the use, of a K&N engine air filter, or the like, I wouldn't tell the Lexus folks.

Replying to: robcanaz (Feb 17, 2009 1:17 pm) Can you tell where the sound is coming from? Engine? Doors? Roof? Ventilation? Other?   tidester, host SUVs and Smart Shopper

Replying to: robcanaz (Feb 17, 2009 1:17 pm) Your whistling noise is likely caused by the positioning of the luggage rails.....try repositioning them more toward the back of the vehicle or, to be sure of the cause, remove all together and test drive. I have a 1999 with the exact same whistle and it proved to the be rails.....good luck! Replies to this message: la4mead (Feb 18, 2009 8:39 am)

Replying to: neumie2000 (Feb 18, 2009 5:36 am) I took my luggage rails off from the beginning. I haven't had a reason to put them back on since. I wonder about trivial things like why anyone keeps them on when not in use in any vehicle. Someday I'll use them again, perhaps. But I'd remove them when done. It's easy. I also wonder how much the small amount of wasted fuel from leaving them up there would add up to after all this time.   Perhaps that's the wind noise you're experiencing, and it's worth looking at.
