air intake control valve number 2

[Abe Scott]

I have 02 rx300 with what I hope is a bad air intake control valve #2.  It is not the air idle control. I can not find the youtube post about this valve. I have replaced the O2 sensors a couple of times. Vsc and CEL lights will stay off for a short time after replacing O2 sensor.  The transmission shifts fine as long as there are no lights on. When the lights come on, the next stop.  The transmission. Upon moving fails to shift into overdrive.  And it shifts hard. Has anyone had this problem with their 02 RX300
