Which code for EGR? It could be a wiring issue that could potentially affect both tps and EGR. Have you gone through all grounds and cleaned them? The one picture you have of the motor, your alternator wire has a blue butt connector on it. Inspect and all of those. They aren’t the best for connections and prone to failing.

Recap of where we are, you have the truck running, but it’s only with the spout out or do you have it running with the spout in again? Have you tested the TPS? Verify the EGR is closed at least and not stuck open. You can look with it still on and see if it moves when vacuum is applied and removed.

Far as I know. I checked codes for key off ignition on, while running, and continuous memory and saw nothing on it. Plus the tests I ran to check it a while ago.

I would check it coming out of the Tfi module. You either have a bad pip, Tfi, broken wire or computer.

Far as I remember checking there wasnt anything wrong with the tfi either when I ran all the tests a while ago. I kinda doubt it but I'm kinda wonderin if the egr bein stuck to some capacity is making the computer have a stroke trying to adjust for it while its connected

It won’t cause the issue of the vehicle only running with the spout removed. It would effect idle, but that’s all.
Computer, pip/distro, Tfi or wiring in that system.

With Rpm’s up and misfiring or is it smooth? If it’s smooth, I would start verifying the EGR isn’t the problem. Quick way to know… take a coke can and cut a section bigger than the EGR port, loosen the EGR bolts and slip it between the EGR and intake, tighten bolts. It don’t matter which side of the gasket, just has to block any chance the EGR is stuck open and allowing air.
check fuel pressure if EGR doesn’t change anything.

I'll hang onto my can from lunch tomorrow and use it Saturday barring the supposed rain we may get. I would assume if it does something its stuck open and if it does nothing its closed?

Alrighty. I'll get back when I can get that tested. Thank you for all the help you've been. Honestly if I had a way to repay you I would cause advice and suggestions go a long way.
