Alright, so my buddy has had limited time but here’s the story as if today.Wired a manual glow plug set up. Got it 100% better. Idles our the smoke and toughness in 30secs or less of on off on off 5sec intervals on the glow plugs. Not my experience with the truck before, but with the slight change in compression, I could just have a more cold natured engine now.The misfire, now, this is a doozy. At one point in the constant airing out of my injectors trying to trouble shoot the fuel issue, I broke the return rail I had been using. I had two extra, got one, cleaned it up, shot some brake cleaner through all the channels, seemed fine to me, put it on, continued my troubleshooting.So my buddy is going to attempt to air out the lines after driving it till it misfired, and breaks the return rail loosening the injection pipe on injector 1. Truck immediately starts idleing perfectly. Takes it apart and examines it. Lead was actually in the piping where they had soldered it together. Limiting the cooling capacity of injector 1, it was sticking and misfiring at operating temp. Cooling down eventually in idle, driving good again, till it sticks, repeat, etc.So, now I am an EGT gauge away from driving the hell out of it. He says it drives better and harder than it did when he sold it to me now. Can’t wait to get out and rip around in it.Really appreciate everyone taking the time to read this and drop suggestions. Only way I even had an idea to try at times, was you guys here. Thanks.
