Hey
I have a 97 Lexus ES 300, and I am having problems at idling, sometimes, its real low and has come to stall few times while trying to go n reverse, also the CEL turn on a couple of days ago, had check it, and its showing up the
code -PO 446 Vent Solenoid Problem-

Could somebody help me here and tell me :
- What is the problem ?
- What could be the causes ?
- what part(s) does that have to be with ?
- how can I troubleshoot it ?
- and if there's just one and not too expensive solution to this problem instead of suggesting taking it to the dealer ?

Thanks in advance.
