I know you guys haven't been on this thread for quite some time, but now I'm having the same exact issues with my RX300! I've replaced all 6 coils and plugs, mass air flow sensor, both of the cam shaft position sensors, and we tested both of the ocv's to see if they were working and both appear to be working. We also cleaned them. Should I go ahead and replace them even though they are getting voltage, are moving, and have been cleaned??? Also, do I need to change my oxygen sensors? There are 4 of them at $170 a piece!! Please help if you can!! Thank you so much!
