There is an adjustment screw on the front of the throttle body. It faces the

A question. I'm assuming it's a MkII, and don't the MkII's have
an IAC (idle air control)?
On many (my experience is with a GM truck) the throttle stop is there to
adjust the throttle plate for vacuum port control, not idle speed. Getting
that messed up can cause some real issues with the transition off of idle.
I might be off base here, but that issue should be checked out before you
break the seal on an adjustment screw. Someone did that on my truck and
I haven't been able to get it right (and the %^&* manual says that only
the dealer can set it, no info on how it should be set).
