I've had a similar rough warm idle problem for the last year, I am going nuts trying to solve it. I have tried all 3 of the CPS's and am now running the original black, and although this solves the cylinder contribution issue on 3 and 8 it did not change the idle whatsoever. I have a new IPR, new ICP, new injectors. I'm still using a fair amount of oil (prob. 1 qt every 1000) and have my rough warm idle. Different tunes from different companies (DP-tuner and BDP) haven't made a difference either.
