my truck hesitates or shudders from 1800 to 2200. FP 20 idle 13 wot. is seams to only do it if the edge is above lv 0. if you let off to idle it idles ruff almost like a lope if you rev it up it gos away. its diving me nuts need help!

Have you tried removing the Edge completely to see if the issue goes away? Does it smoke at all? If so, what color smoke? Any trouble codes stored in the computer?

Sounds like an Edge problem. Do like Will said and pull the Edge and see what happens.

I have qwad, and had same problem, changed injectors immediately went away, a year later it's back. Not sure if I'm helping but keep us posted.

Codes?
