Mine has 84,000. The same thing happened to mine. Two things you can do:
1) Unhook your car battery for half an hour and see if that fixes it. 2) Change your oil.Strangely enough changing my oil fixed the problem.
Get your hands on an OBDII reader and see what the code is that set the light. Try a local auto parts store, they may read it for you for nothing.

I took my Trooper to a dealer who plugged in and read the code for free.
The most common problem on older model Isuzus is a leak in the pressurized fuel system - environmental system. Check to assure the fuel cap is on tight; look for leaks in the fuel cap and buy a new one ($10) if necessary.
The "check engine" light on my '97 Trooper came on at 86K miles. It was the oxygen sensor.
