Instead of using two cycle oil, try Waste veggie oil filtered. I run B20 in the am and pm on start up for the day and shut down for the day.
Other than that she runs on the lubricating properties of veggie.

I skimmed through this thread, I went through the same issue in the past last year, in the morning when cold it would idle fine, when hot after a long drive it would lope and stumble pretty hard, after a couple of months of figuring it out which included ohming out my injectors, checking the wiring, adding a HPX line, shimming the regulator, all which give a suddle improvment but never solved the problem I said screw it and I started pulling my injectors out. turned out I had 2 bad o-rings on my injector o-rings and a third that was ever so starting to detoriate. changed the injector o-rings and has idled great since.
Cover your bases first before running after the injector o-rings, but that was my problem and I had no fuel in my oil and what I had gathered is when the engine was hot and the oil had thinned it would cause issues, thats my theory of course.

The blown engine I pulled out 8 weeks ago in a e-350 was a direct cause of blown injector o-rings, oil flowed like water and was nearly clear.

I may have found the problem. For poops and giggles, I changed the EGR sensor with a new one, and it appears that my idle problems have gone away. It is running very smooth, hot, or cold. Interesting................
