Yup, that's a BVSV. It at the very least should help a little, although I can't say for sure if it'll completely fix it.

Actually, since you capped off the lines it probably won't change the revving. It will, however, help your evaporative emissions system work properly.

Since there are quite a few vacuum lines on the car, I'd suggest spending some time running through the engine bay and checking that everything is hooked up properly. I had to do this on my first 87 (N/A), and it really didn't take that long.

Click here for the vacuum routing diagram (note that this includes all the lines connected to the engine, but not all of them in the engine bay). Thanks to green7mgte for the link in another thread.
