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.

Good luck.

SOURCE: IAT sensor

The intake air temperature sensor can be found in the air intake duct, or threaded into the intake manifold depending on which engine you have.

It should do unless the gauges or boken/loose wire was the original fault

SOURCE: alternator belt diagram 1992 Isuzu trooper

1. Remove battery terminals and secure them away from the battery posts using nylon wire ties.

1a. Fine some comfortable eye glasses (clear or yellow) and keep them on. There are plenty of opportunities to get debris in your eyes during this procedure.

2. Spray "PB Blaster" (loosens bolts) on two bolts that secures alternator.

3. Jack-up vehicle on side to access alternator. Use a jackstand to support.

4. Using a 10mm open-ended wrench, loosen the bolt that swings the alternator. Screwing the bolt "in" or toward the engine will allow play to increase in the alternator belt. Loosen the 12mm bolt slightly next to the 10mm bolt (approximately 1.5" toward engine).

5. Continue to loosen 10mm bolt until there is enough slack in the belt to remove the belt from the alternator pulley.

6. Remove belt. It may be possible to remove belt without removing fan faring. Maybe not. If not, you will need to remove plastic fairing. If you must remove fair, go below fan fairing and disassemble connectors that hold together pieces of fan fairing. Carefully remove.

7. Install alternator fan from above.

8. Check that alternator belt is on all tracks (from below with a flashlight), and slowly tighten.

9. Secure 10mm and 12mm bolts. Recheck tightness.

10. Reassemble battery connection and run vehicle at idle for about 5 minutes. Check belt for proper tension.

11. CAREFULLY check tension of belt. Or disassemble battery connections and re-check belt tension.

12. Reassemble fan fairing (if not already assembled), re-connect battery terminals, and have a nice day. :-)

SOURCE: How to clean EGR valve passages in 1993 Isuzu Trooper DOHC V6

You have to the EGR valve (sometimes the Intake manifold to EGR Vlalve line also). After you remove it take a drill bit the about 20 % smaller than the actual hole of the outlet side and rotate the drill bit with your hand to dig out the carbon. Aditionally the line coming from the intake manifold to the EGR valve will clog near the connection to the EGR valve. I use either a single piece of copper wire or the wire that you would use to tie ribar together to clean the line. When your done cleaning take a piece of vacuum line and connect it to the diaphram side and **** on it... then plug the line well with your thumb. Grasp the valve and blow thru it... Air should blow thru it freely. Remove your thumb from the vacuum line and try blowing again.. No air should pass thru the valve.
Then reinstall the valve and start the vehicle with the vacuum line disconnected (but blocked off) Use another piece of vacuum line connected to the diaphram again and **** on the line.. The vehicle should die or run really bad. If it does this then you cleaned it correctly.

I have isuzu bighorn '92 model automatic,there is a leaking oil under the intercooler turbo...is this normal?thanks.


Leaking of any fluid is not normal. The only time any fluid should expel from the car is if you have overfilled something. Your turbo could need replacing, you could have a hole in the intercooler. Have you noticed any lack of performance or extra smoke...

94 trooper startsbut stalls immediatly-changed throttle position sensor,map sensor, and idle air control valve but problem continues


I can't remember exactly, but if there is an airflow meter, check the air intake hose for cracks or looseness. If there is any openings between the throttle body and the airflow meter, the computer will not see the air entering the engine so it will stall right after it starts.

Isuzu trooper starts briefly then dies


check your fuel delivery from the pump to the "dry" pulsing injectors leave the crank sensor alone! open the intake and, spray either (engine start) into the engine then attempt to start; it should start and, run until the either is used up then die. most likely your fuel filters are clogged

Unstable RPM - is this also a safety issue??


yes here is the common problem

Here is the most common cause of surges and stalls and low idle rough idle, it is the idle speed control air-bypass valve and throttle valve (IAC for short), they get full of gunk over the miles and cause idle issues (stalls, low idle) like yours, Get a can of intake cleaner from any local parts store, not carb spray, intake cleaner, it is made by a company called CRC, remove the air intake hose to the engine, hold the idle high so the engine won't stall, then spray the can of cleaner into the intake while keeping the engine running, use at least 1/2 the can, shut down the engine and disconnect the battery for 5 minutes, then restart and complete a number of mixed driving cycles, town, freeway, stop and go etc., after a few days the problem will go away as the system will relearn to the clean intake.
