Tone-----I agree, I am actually glad the Interceptor is not the cause because I like it.
Joe-----I have not rechecked the fluid, and yes I agree I need to get that checked still. I still get the feeling (backyard mechanic) that nothing mechanical is wrong (major parts anyway). I cant explain it, just a gut feeling. I get the feeling its electrical or vacuum related, of course thats assuming the tranny fluid checks out.

I had some minor issues with the Interceptor and removed it. Used it for damn near 3 years and loved it. Made a small, but noticable difference. I started getting some shift lags and downshifting started getting rough, so I removed it. SHifting was back to being smoother once removed. After further inspection of the module, it was pretty war-torn from road wear. I suspect being open to elements (tie fastened to frame) for some time may have caused some issues for it. Winters with rock salt and sand, as well as rain and high heat in other months of the year (basically, east coast seasons) are probably not gonna mesh well with prolonged exposure with the module.
Just a guess in my case since the module was pretty rough looking.

Ok, this makes absolutely no sense to me but, I am glad to say the problem seems to be resolved. I feel a little relieved, aggrevated, and stupified all at the same time.
It seems the problem was something I had problems with in the past. Basically it boils down to the EGR. In the past I have had problems with the bottom (22m) nut coming loose due to vibration, well this caused no noticable problems except the slight exhaust leak sound while driving. I was out driving the other day and noticed the same exhaust sound I had heard in the past (at this time is still have the erratic rpm guage, abs light, occasional downshift, and engine stumble) so I decided to pull over and tighten the bolt, since I learned from past experience to carry the required 22m stubby with me. Much to my suprise I noticed the 2 allen bolts for the pipe between the egr and the s/c were also loose at the EGR block. Unable to tighten these out on the roadway, I drove home with them loose still (with the same problems I had been having). Soon as the engine cooled off enough I tightened them back up. Well its been 4 days later and everything is completely back to normal, no erratic rpm guage, no abs light, no downshifting, or stumbling.
How a simple air leak can cause soo many different issues, I'll never know, but I am glad it was an easy fix. Just wanted to let everyone know, if any of the symptoms are ahowing, check the EGR fitting closely.

It just freaks the sensors out and the ECU simply isn't the smartest thing in the world. Get outside of its computational box and it'll torture your engine trying to rid itself of the demons it thinks it "sees".Originally Posted by Ruflyf
Thankfully I've never had an EGR issue with any of my Isuzus, but I almost wish I would just as an excuse to remove the EGR and replace with some block-off plates and an EGR simulator.
Actually, my plan is to use MegaSquirt for the rally VX which could possibly open up a whole new realm of possibilities for everyone interested in taking control of their engine management.
In any case, hopefully this resolves your issues and you can just button those fasteners up with some HD LocTite and drive happy.

So this screw is directly underneath the egr? I think this is my problem too. My truck if not normally supposed to sound like this, sounds more diesel iv noticed......
The bolt that is 22m is under the EGR block. The 2 hex nuts are on the engine side of the block that the EGR attaches to. The lower bolt just caused a exhaust leak sound. The other two hex bolts being loose caused all the other issues.
