I had a similar problem. I found the filter cartridge below the pcv valve had carboned up, and after the crank case pressurized, oil was forced out the pcv supply line to the throttle body. The idle air control valve solenoid got oil in it and caused my problem, but only when it was cold. The pcv cartridge is accessed by removing the pcv valve and the rubber fitting that the pcv valve mounts in. It can then be fished out with a pick set, and it is a pain because you can't see it, but you can get you hand back there. I hope this helps you.

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.

The battery could still be bad and if you don't have a totally good battery in the car it won't run right. Take to one of the parts stores and they can check it for you for free. Probably as simple as a battery.
