Test it and see if it can be properly adjusted. If not, then you know it is bad and needs to be replaced:

well, not to rain on your parade, although I'm sure the satisfaction is worthwhile... and well deserved.
The idle should not be hunting from 600-850. it should be all but rock solid.
so maybe now that the conditions are different, a timing check and idle adjustment are once again in order. and then a cursory check for more vacuum leaks.

After checking. The 3vze is supposed to be at 10' BTDC with the jumper installed with and idle speed of 800 rpms

Well, I wont be able to get a timing light till next week at the earliest.
I am totally not interested in touching this damn truck for awhile.... I have delt with this idle problem for over a year and a half.
I guess when I get a timing light I will check the timing with the connectors jumped and not jumped..

my truck is having kinda the same problems, i.e. i went wheeling today and the second half of the trip my tack read almost 0! So i think the o2 sensor may be part of the problem cause mines not even attached. so maybe yours went bad too

I actually tested the o2 sensor ( I have a replacement NTK but I cannot remove the old one!) and it tested perfect..
I have narrowed the problem down to (I think) a bad TPS wire. The VC (IIRC) wire from the ECM to the TPS is reading little continuity on my Ohm meter.
I scraped off some of the insulator on the vc wire before each connector. I then attached a test wire from the ECM side to the TPS side.
This yeilded a very smooth idle, and the idle dropped with the Te1 and e1 connectors.
So I found this out over a month ago, and I have still not fixed it. Im honestly not too excited to remove the metric assload of parts to get wiring harness open enough so I can replace that single wire.
Anyone wanna do it for me?
I also want to note I have still not checked the timing, I totally forgot.
