Throttle on 93 Five Speed

I have a standard and the revs seem to stay too high between shifts, like the throttle is sticking. Anyone have an idea about this? Seems I had this problem on my 92, but I can't remember what I did about it.

Does it idle high while you sit at the light?

No, it idles fine when sitting. No surges and not too high. Seems to be just when shifting.
