There are service bulletins at Isuzu for this. If this is your engine, this may help. The advice Boxtrooper gave you is real good and will help you find the components . Good Luck.
1995 Isuzu Truck Trooper (4 Door) V6-3165cc 3.2L DOHC (6VD1)
Vehicle Level Powertrain Management Fuel Delivery and Air Induction Throttle Cable/Linkage Technical Service Bulletins Recalls Recall 04V199000: Accelerator Cable Sticking
Recall 04V199000: Accelerator Cable Sticking
DEFECT: On certain sport utility vehicles, the accelerator cable can stick so that the engine speed will not immediately decrease upon release of the accelerator pedal. This can cause the accelerator throttle cable to delay rpm and vehicle speed reduction for several seconds after the accelerator pedal is released, which in turn, can lead to a crash.
REMEDY: Dealers will replace the throttle cable rubber boot. The manufacturer has reported that owner notification is expected to begin during May 2004. Owners may contact Isuzu at 1-800-255-6727.
1992-1995 Isuzu Trooper Accelerator Cable Safety Campaign
ISSUE DATE: MAY 2004
Campaign Identification Number
Number 04V-199 has been assigned to this campaign by the National Highway Traffic Safety Administration (NHTSA). This number will appear on all communications and documentation of any nature dealing with the campaign.
1992-1995 Isuzu Trooper (UX) vehicles equipped with V6 engines with the following VIN range JACDH58V7N7900012 - JACDJ58V5S7906162.
On some vehicles, the accelerator cable dust cover may deteriorate, causing the cable dust cover to adhere to the inner throttle cable. This can cause the accelerator throttle cable to delay RPM and vehicle speed reduction for several seconds after the accelerator pedal is released, which in turn, can lead to a crash without warning.
Follow the service procedure in this bulletin to replace the accelerator cable dust cover.
Isuzu dealers are required to service all eligible vehicles at no charge to the owner, regardless of mileage, age of vehicle or ownership.
Whenever a vehicle subject to this campaign is in a dealer's vehicle inventory or arrives at the dealership for service, the dealer must take the necessary steps to ensure that this campaign correction has been made before selling or releasing the vehicle.
Each Isuzu dealer will be supplied a copy of the AIMI Campaign Report (AWS-123-1A) listing affected vehicles assigned to that dealership. The report contains VIN and detailed owner information obtained from state motor vehicle registration records. The use of such motor vehicle registration data for any other purpose is a violation of the law in several states. Accordingly, dealers are urged to limit the use of this listing to the follow-up necessary to complete this campaign. If none of the affected vehicles are assigned to a dealership, no campaign report will be sent.
Isuzu Motors America, Inc. will send a notification letter to owners of affected vehicles already retailed (see enclosed copy). Dealers should follow up with vehicle owners by sending a Campaign Reminder Notice (AIMI SVCF-1052) to all vehicle owners listed in the AIMI Campaign Report (AWS-123-1A). Dealers may obtain these postcards from their Regional Office.
Applying the Campaign Label
Affix the campaign label P/N 2-90028-700-0 adjacent to the manufacturer's identification label located inside the driver's door. Using a ballpoint pen, fill in the label with campaign number 04V-199, Isuzu dealer code and repair date.
Warranty Claim Information
Use the labor operation shown.
1. Labor Time includes administrative time allowance.
2. Information released on paper and electronic format prior to bulletin release cannot be updated.
3. Always refer to the Isuzu Service Policy Procedure Manual for specific details on warranty coverage and policies.

As a follow up to your problem, check the vehicle ID number yourself to see if you got the right info from the dealer. They should fix it if your VIN falls within the guidelines of the recall. If not, as a follow up to boxtrooper, I can post a picture of the cable parts, just let us know.

My 86 Trooper only has wipers on high speed. Nothing on intermintent nor slow speed. I was thinking of the combination switch being shot but before I replace this rather pricey switch, is it possibe that there is a relay in the circuit that could be failing? If so, where is it? Thanks.

Since the VIN range for the recall is
JACDH58V7N7900012 - JACDJ58V5S7906162, and my VIN is:
Then it stands to reason that my vehicle should be covered by this recall and the Isuzu guy I spoke to was wrong. Thanks for your help, I'll give them another call. If they still don't budge, I'll follow your suggestions.

Hi, I am not personally familiar with your year and model, but I did a little research and found a schematic of the wiper washer system. The service manual refers to a wiper relay but I could not find it in the schematic, which is kind of a unique situation. I am not a whiz at troubleshooting by paper, so maybe looking at the diagram can help you. These two locations have the wiring pictures. You may have to enlarge them but they seem pretty easy to read. It does appear to me that it could be the motor or the switch, as the motor may have the relay in it or as part of it and the diagram shows different contacts for speed control. Good Luck.

I had the same problem " run 3-5 seconds and quit" with my 89 2.6 fuel injected trooper, after toying with different things I saw online changed out the fuel pump 300+, fuel regulator 20 and the thought of changing out the ecu $$$, not to mention the countless hours of beating my head off the hood for buying this thing, :off a hunch: I pulled the fuel pump relay out. ( now hear me out ) pop the cover off the top of the relay, you will find a spring in there, carefully stretch the spring out a bit so the electromagnet doesn't have to pull as hard to keep the truck running. THAT IS ALL I DID AND I HAVE NOT HAD A PROBLEM KEEPING THE TRUCK RUNNING SINCE.... sounds retarded but with the computer problems on these trucks it's a very cheap fix

Just got off the phone with Isuzu customer support. They say that even though my VIN is within the VIN range, that the production date for the recall was through January of 1995, and my vehicle was mfg'd in July of '95, and is thus not covered. If it wouldn't be too much trouble for you to post the cable part pic, I'd really appreciate it.
Thanks again for your help!

Really sorry to hear Isuzu would not help you. I have posted two diagrams of the cable and adjustment procedure. The link to the pics are: http://www.carspace.com/atfdmike/.59a212fb
To adjust to factory specs, do the following after you complete repairs, refer to diagram showing cable adjusting nuts and:
Loosen adjusting nut.
Lock throttle valve fully closed and pull outer cable.
Adjust nut "B" so that clearance is as shown.
Push nut "B" against bracket and tighten nut "A" to lock cable.
I hope this information helps you. You may well need to spend quite some time to determine which part is binding and then fix it. It is too dangerous, as you know, not to do it right. Best of Luck!

Thanks for these! While I was at lunch today, I thought I'd poke around and see if I could figure out what was binding. At first, it seemed like something inside. There was kind of a hanging point before I could press the pedal all the way, then the pedal was held up on its return to the original position. I opened the hood and looked at where the throttle cable attaches. What I found was exactly what the Isuzu recall was for. The dust cover over the end of the throttle cable sheath had come loose and seemed to be partially melted. The inner cable was covered in sticky black stuff, which I assume is the rubber from the dust cover. I removed the dust cover until I can get a new one and cleaned the rubber off the cable. RPMs seem to be dropping properly now and there is no more binding in either direction.
Thanks again for your help!
