That's kind of how I feel about my idle, all the more so after adding my A/C and the extra load it brings. Unfortunately I only have myself to blame about it though since it's my own tune, lol. I really just need to spend some quality time with a laptop and a couple gallons of gas to sit in the driveway and try to work it out. I've messed with some of my PID settings and gotten things better, but I think I need to do some more work on the fuel and ignition table first as it's really swinging the AFR around more than it used to and the closed loop idle control is just a band-aid. Happens the most when I'm in a drive thru or something like that with a lot of little throttle stabs and clutching in and out. Doesn't look very cool when you have to swap feet reel quick and panic stab the throttle while getting off the clutch and onto the brake with your other foot so you don't roll into the cars around you. Or when it just flat out dies because you didn't catch it. I'm also torn because I have a cam in the car and I'd like to keep the cam sound, but at the same time I'd like a "stable" idle. I've been trying to find the right closed loop settings that will let it have some rpm swing for the chop, but is sensitive enough to catch it when it dips too far.
