I am having a similar problem. I have a 1996 Isuzu Trooper LS. Whenever I drive my car and it has been sitting for a while (~12 hours or longer) the engine kicks hard into second gear. Then into third gear it really slams hard. On the down shift, it reverses...kicks hard down to second and slams harder back into first. After I drive around for 10 minutes or so, if I re start my engine, the problem goes away ??? It was doing this last year and then just went away. Last year it lasted about 3 weeks. I think I know what is causing the problem. Both of these occurrences started after I had been driving in flooded streets. The sensor problem discussed in the message that I am replying to sounds like it may fix my problem. If you have photos and are willing to help, I would greatly appreciate it. I was thinking that I may have solved the problem the first time because shortly after it started kicking...about two weeks....The starter went on it and I think when they were working on it, the car computer got reset. Is there a way for me to reset my computer quickly and cheaply just to see if this will fix my problem ? Can I just disconnect my negative battery cable for a while? I did try this and it didn't work. I may not have had the cable disconnected for long enough time as my clock wasn't flashing when I reconnected it. As a temporary fix, I am driving my car for 10-15 minutes before I go to bed and that keeps it warm enough for it not to kick when I drive it the next morning. Please help me, my trooper is ill !!!

I just got a special buy back program for 1999 Troopers...due to a "special used vehicle request"...of course they said come trade it in for a new vehicle.
I don't want to get rid of it, but faced with a transfer case problem...I am interested in just getting good cash for it...I am going to call them regarding them just buying it back without getting a lincoln/mercury...just the $$$. If the deal is good I might take them up on it.
What do you think $6500 would be a sell it on the spot price? Anyone else hear of a special buy back or do you think this is just a sales gimmick? Probably just a gimmick, but who would want 1999 troopers used on their lot?

Yeah, I figure as much...and no offense to lincoln/mercury people...but those are not something I am interested in. Straight cash and good cash I am interested.
I like my Isuzu, but the future is uncertain. I always thought I would keep it until the wheels fell off...but now I need to know that when I go offroading with my family on vacation 3000 miles from home, I cannot have an old car problem. That is the rub...great 4 wheeler, poor service and no confidence in the dealer network...means get a 4runner if possible. (at least to me)

It's a scam. Be afraid . . . be very afraid . . .

I had the same problem that manifested itself on a long trip. '99 Trooper with 70k miles. It progressively got worse to the point that I had to keep the tank full of fuel for it to run correctly. I got the same codes. The solution was to replace the fuel pump and fuel filter. The in-tank screen gets clogged with crap to the point that the pump cannot pump enough fuel without the pressure of a full tank.
Dropping the tank and replacing the pump took me about 41/2 hours. Took it on a highway trip today and it ran great. I'm 95% sure this is your problem.
#11002 of 11965 Inside Mirror Removal
Oct 17, 2005 (1:13 pm)
Anybody know how to remove the inside rear view mirror on a '01 Trooper? I'm thinking about replacing it with one the the Gentex auto dim/temp/compass mirrors. There is a plastic housing covering the mounting point at the edge of the headliner, but I can't figure out how to get it off.
While I'm at it, my Trooper (LS with sunroof) already has the wiring harness and temp probe pre-installed for an overhead "multimeter". I think these can be used with the Gentex mirror. My harness wires aren't labeled. How do I determine which ones are for the temp probe, hot lead and ground?

Michael - Forgive me for being so naive as I am a chick and normally do not surf such sites. However this has been quite resourceful. I'm assuming there is a diagnostic machine that spits out these fault codes. Are they available at most garages or at dealers and specialty garages. I have tried a fuel additive/cleaner to try to clear up my stalling problem as I run my fuel tank kind of low. My injectors are probably due for a cleaning as well. I am checking my records to see when the last time a changed the fuel filter. At any rate, I'm interested in pulling a diagnostic test to see what errors may come up.
#11004 of 11965 CODES for paratrooper

If you have an Autozone nearby, they can usually pull the codes for you as a courtesy. That's where I'd start out.

The fuel filter is a large inline unit below the right rear door, it is an easy DIY and not expensive. I usually change the fuel filter when it gets cold for winter to prevent freezing in the fuel filter paper which might absorb water.
Also, for fuel injector cleaning, have you tried a fuel additive such as the ones from Valvoline or RedLineOil in the strength recommended for annual application? I havwe found that fuel injector cleaner helps prevent hesitation on my manual 5 speed, and that hesitation could show up at a stall if load was applied too quickly as an automatic transmission might do.
