Edit: Just confirmed it - it was 33. "EGR Valve opening not detected."
When I return home, I plan to take off the valve and try cleaning it. I just put it on the back burner because the truck IS running and I need to get the massive wrench to be able to take the valve off.
But are those symptoms common to a bad EGR valve? The idle surge, not being able to start the truck sometimes, and turning off while running? From the research I've read about the EGR valve, it makes sense to me. I am returning home tonight and will post back as soon as I am able to clean this stupid valve. It will be soon seeing as how I need this truck to MOVE in a week. lol

And gtyjf1 - Have you tried getting any trouble codes? The way I found out it was my ECU was doing that. I didn't get ANY codes. Even if you disconnect your battery, it should give you an "11" or "111" meaning "all systems pass". But I got nothing... meaning the ECU had been fried. Always try and do trouble codes first. Unfortunately for me, I decided to do this after I had replaced basically the whole ignition system.
But any help on my truck shutting off would be helpful. Thanks!

I'm not at home right now... not even in my home state. So I don't have the trouble codes that I wrote down. But from memory I am pretty sure it was 33.

That, or the EGR regulator that activates the valve. Take the vac hose off the EGR at warm idle. Should be no Vac. take rpm up to 2K. Got Vac now? No other codes? The ECU is a possibility if it's randomly deciding to now trigger the injectors. Did you take the TFI in to be checked?
I'll try the vacuum tests. I did the ones in the Haynes manual and again - pointing to EGR valve. And another ECU problem is the last thing I need to hear right now. lol
TFI is brand new.
