I had the same trouble with my 93 Trooper.
I went on a sensor-changing spree.
The one sensor that fixed this idle problem was the throttle position sensor.
You can get one here.
Throttle Position Sensor
It's very easy to change, and fixes the problem instantly.

I had the same issue on my 99 Trooper.
It would usually start when completely cold, but idle around 2k RPM.
It would drive fine. But if I shut it down, ran into a store, and came back out, it would start but immediately idle.
Had to ride the gas a little to get it into gear.
The Check Engine light has been going on and off for 6 months or so.
I took this to my local trusted repair shop (no Isuzu dealers within 200 miles).
The diagnosed the light, and found that the Intake Gaskets were bad or leaking.
The idling problem was related to the car not being able to control the amount of air coming in.
They replaced the Intake gaskets by the next day, and I haven't had a problem since. And no more check engine light, which has been on half a year.
Here's some details from my bill:
(1) Intake Gasket set $107.95
Misc materials $21.00
2.1 hours of Labor
The total cost to me was $345.00, and I definately don't feel gipped.
