My Yukon idles/runs rough when I initially start (cold), after it warms up it runs great. Shaky and rough running is only for a few minutes after starting when sitting long or cold. I heard something about cleaning or wiping out (some part?) That gets gummed up, could that be the issue? Can anyone please advie?
Thanks in advance.
