Is it ok to take the throttle body off the car, flush it out with carb cleaner and water, and just let it dry?

 

as long as its dry when u put it back in.

 

Yes, I have done that a few times (though not to my own RX300) but a few other vehicles I have worked on.

 

I personally wouldnt use water. I would use the carb choke and compressed air.

 

here's the catch. my idle is very rough at this moment, and my vsc/vsc off lights are both on. I do have an AEM intake, so I'm going to go back to stock when I get home and see if it still idles roughly. If it still does then I'm going to take a look at my throttle body (praying that it is not bad).
