The thermal vacuum switch is responsible for controlling the 4ZE1 & 4ZD1 engine idle during specific parameters of the engine operation. There are only 5 vehicles that use this same part that I know of. Unfortunately none of them are easier or cheaper to purchase. What is available are used parts that normally are not in any better condition than your 30+ year old part you already own. Now there is a solution to this ongoing problem.

It's taken countless hours of research, tracing the origins of Isuzu engines for clues on how to write the correct code, experimenting, purchasing ECMs and cables and software to be able to retune Isuzu's ECMs. I have destroyed over 15 ECM one laptop computer and 3 programmers in this quest to make it all possible. I have taken a lot of shit from people who don't believe that this is even possible. All because with a big bark say dumb stuff such as "it's not possible." Or they say " If it...

At this moment in time I am simply letting it be known to all Isuzu people that a aftermarket product believed to have never existed for this engine is currently in production. It's made by several companies & production started well over 40 years ago too. This particular model is the cheapest I could find. Interesting fact there is no listing for the 4ZE1 engine, it's listed under the 4ze1 sister engine that is also believed not to exist... 4ZE1 dual carburetor performance intake manifold ..read more

Hi all, new here! As a retirement (injury) gig, I build weird campers out of weird trucks. I've done a M109A3, a "stealth" box truck, and a 2nd gen Ram with a cab swap and habitat built on the back. Now, finally have the ultimate weirdo. I built a camper out of a Tru-Green Isuzu NPR Rhino. I build them to sell but I REALLY love the NPRs. So, it's done but the more I drive it, the more I love it. I've researched for years on doing the 4x4 conversion and the one thing that stopped me was the... NPR Crossover steering conversion ..read more

I currently have a 97 Rodeo Dana 44 in my Amigo. I have broken one of the axle shafts and was looking for Chromoly shafts, which I haven't been able to find, stock replacements seem to been troublesome to locate also. Anyone know of a source for either type of axle or a cross over for the Dana 44 axle? Just seems like there should be another Dana 44 axle assemble that would use the same axle. Thanks ..read more

I've got some questions y'all may be able to help me out with. I've got an 01 amigo and I'm wanting to eventually put an elocker in my rear 44. Before I go to actually buy one I would love some clarification on fitment (and perhaps axle specs). I was thinking of getting this guy, 19977-010 | Eaton ELocker Differential | Eaton, but I haven't gotten confirmation and I don't want to spend all that money on something I don't know...
