Also may be that the idle switch adjustment is on edge.  In fact that
would be my first suspicion.  The 2.1l won't idle down unless that
switch is closed.

Tap into the two wires, run a pair up front and stick a small yellow
LED from the Radio Shack assortment on it.  If you don't get bright
yellow with open throttle then it's wrong way around.  At full
throttle and closed throttle the LED should go out, or nearly.  With
the light up in the cab you can drive it and see if that's your issue
(assuming that you find the cable isn't too tight).

If it does need adjusting, come back and talk about it first.  It's
delicate and expensive and the book procedure isn't sufficient on a
worn throttle body.
