From my experience you are seriously S.O.L I have seen this disscussion come up quite a few times and have brought it up myself a couple. My truck - a 1997 K1500 with the 350 Vortec - has done the same from shortly after purchase. I have tried spark plugs, fuel filter, and have tried to find any vacum leaks, all with no change. I am hoping its just the nature of the beast and not a symptom of some problem starting. Some have suggested that this is the start of the infamous intake leak but so far I can see no evidence of this but I am keeping my fingers crossed.

Let us know if you come up with any solutions, i'm willing to give anything a try. Love my truck but sometimes this problem drives me crazy.

I hear ya... It doesnt effect performance any.. just annoying at Idle.. I also tested for vacuum leaks and all the common causes.. but thank you for your reply and if someday I do figure it out.. I will let ya know.
