Still Rough Idle?

man, i can't get this whipped! i am still getting a rough idle at times. no matter the chip setting, even with new Fuel Filter, cleaned FPR screen, and all that. what do i check now? its also a little choppy when revving it up and holding it a little high RPMs to jump start someone. i just can't figure it out. Ideas?

I have that also-pulled codes and keep getting IDM fault. Buzz test and it fails every time, contribution test passes so I ordered IDM. Do you have access to scanner?

Have you tried unplugging the ICP when it is running rough? If the idle smooths out when you unplug it then the ICP is bad.
