Clean the Valva and it should solve the problem. Take off the air filter box lid. Remove the air filter box along with the filter. Remove air hose which is attached to intake / throttle body. Remove th valve....note..the phillips head screws are easy to strip so make sure you have the proper size phillips head screw driver. Clean enitre valve thoroughly with throttle body / carb cleaner. Re-assemble, and this should help eliminate the problem. If not, check for fouled plugs, stretched line from accelerator to throttle control, or fouled coils. what he said also there is a real thin round black gasket... don't loose it!!

I have a 2007 RX 400h with the Levinson sound system. The system identifies the changer as a "DVD Changer," but it appears to only play CDs. Optimally, I would like to use the "DVD Changer" to play MP3s burned to DVDs (as I can get a lot more of them on the DVD). Is there any way to make that work? Nero allows me to burn a "DVD Jukebox" with the MP3s, but the DVD Changer does not appear to recognize the format. Thanks in advance for any insight / assistance that anyone can provide. i am a lexus tech, dont play burned cd's/dvd/s as they are to thick and will be come loged (jammed). is 300 are particullary bad, but i don't recomend it on any model lexus.
