Cody, welcome to the forum. If you go to the Lexus Models/RX forums, you'll find a section with the RX300 owners. That will probably give you more help.

Often in our beloved RX's the OCV's get blocked up from our sludge factory of an engine.
I'd replace them as basic RX maintenance anyways but you can try removing them and cleaning. Though often they "look" ok but in fact are bad.
I'm sure others will chime in with support as well.
