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!

 

Anyone have anything?

 

Found my problem, thanks anyways.

 

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.
