Trying to be thorough so please bare with me...

I changed the spark plugs on my sc300 a few days ago and after I had put everything back together, I noticed that I had a vacuum port missing a line, and so far, haven't been able to find where it leads to. The car starts up and idles a bit high, and has a slight stumble at part throttle, which doesn't surprise me seeing how I believe its part of the traction control.


The port is the "oddball" one on the trac control/throttle body that is angled to the drivers side corner of the car in front of the 3 ports right next to each other. Looking at the diagram on the hood, I saw that it went to one of the 3 "VSV" units, and so far, I haven't been able to find the last one.

I'm guessing that it needs to be buried somewhere where I can't see it because me and a few of my friends have looked for a good minute trying to find that last port. When I changed the spark plugs, I took off the entire "y" pipe and since changing the spark plugs, it has had problems.

Thanks for the help!

lol, thats why i never remove the y part. too many vacuum lines and little stuff.
I just pull off the throttle body the old fashion way while trying not to scratch my turbo.
