So... Its been a long time... I am back from Afghanistan, and the answer I came up with is sort of embarrassing. It turns out the uneven idle goes away in the summer but seems to come back in the winter, could it be the cold? Actually it sort of was the cold, since the idle is only uneven when I have the heated seats on. I can only relate that to some sensor noticing a large draw on the vehicles electrical systems and maybe it compensates by running the motor at a slightly higher RPM, totally speculative, but that's what I came up with, of course after replacing spark plugs and an O2 sensor.
