Speedometer, High RPM/Speed whine, High HC's 88 N/A

After looking at the diagram provided I think I just found out why my HC'sare so bloody high and its so stupid its rediulous:
The second tiny hose from the charcoal canister to the BVSV wasn't connected. I couldn't believe that that could be the cuase of high HC levels but after reading the document it specifically states that the charcoal caister connections are what help reduce HC's...can you believe it? Now to just get my other questions (about the Knock Sensor connection and the strange sound) answered thanks man for your info so far :-) Oh and I should be more clear I have an automatic tranny with overdrive and that power mode thing

I think that just reduces HCs in the long run of the life of the car, But it may help. I dont know when the vaccum switch is open, But i think its just when the car is cold or ot. One of those two. Its temp related. I would say check the output reading from ure 02 sensor with a voltmeter, and then replace it if neccesary.

right and here is why this specifically is screwing me up cuz i just took another look and gues what? The bottom peice to the BVSV is missing. Oh and apparently hasn't been there since i got the car, something each Toyota Technician failed to notice. i amjust as much at fault though.
