I have a 98 trooper and it was doing the same thing, so I asked around at work and a guy with a Mustang used to have the same issue. before it stalls, does the RPM needle bounce, If so, Check you Intake sensor. I sprayed mine with a can of air and have not had a problem since. I also had my Fuel injection cleaned ($50 at jiffy lube) and have been adding a fuel additive and it has be running great for a truck with 140k

I have a 92 Isuzu trooper. In the past if I did not let it run for a few mintues it would die when I stopped. Now, I was just driving along (had driven 30 ate dinner then about 15 later) and it just died. It strarted right up again after it sat for about 15 min. Then a couple of days later I had driven it to work ( no problems) but coming home it died and had to wait 15-20 min. and then it started, it died again a couple of miles later. Let set for about 1 hour and it started right up. My husband changed the fule filter because it would not start at all the next day. I drove to work no problems, coming home filled with gas and would not start for 45 min and then died again 15 miles later. Sat for 20 min and started up and drove the other 15 miles home.

It was a bad wiring harness. Somewhere in the bundle that runs across the top of the engine the wire shorted out. A common problem on this vehicle. Took two months of going thru bad used ones(cannot have any cuts because some cables are shielded) which I had to find throughout the country on my own. I finally found a new one on my one at a dealership in Mass. Isuzu did not produce the part any longer and had no time frame on producing it. Isuzu reps were terrible and did not get back with me on several occasions.

thanks man. today i run another test it gave me codes PO300, PO 505, PO171 and PO1340. What codes gave to you when you had the problem. For the cables that you talk about, are those the ones that connect to a little box in top of the engine?

I cant remember the codes. Just take it to an isuzu dealership and the will have the info you need. Yes it runs atop the engine. It is a bundle of wires(part #8-97148-639-8-Costs $413.46, paid $330 from Seekonk Isuzu 401-434-6985) that comes of your fuse box inside the engine and spiders out throughout every sensor/electrical device under the hood. The wires that normally go bad runs in a black plastic tray on top of the engine. Which is extremely hot while running.

I have the same problem with my 94 trooper. Does anyone have an idea why the stalling is intermittent?

#11 of 39 Trooper Stalling with no warning by takohunter

Jun 01, 2008 (11:21 pm)

I have a 1994 trooper and recently it has been stalling on me without any warning. After it stalls and I re-try to start it, the RPM needles flutters and then the car dies out. After waiting about 15-20 minutes, I can start the car and then it runs normal again. I took it to a mechanic and could nnot find the problem as it only occurs randomly. Does anyone else have this problem? A couple of people said it could be the fuel filter or pump and that I should also get a tune up. nother person thinks it could be the ignition coil. I am not mechanically versed so can anyone help me.
