Recently I have started having issues with my idle when the engine is first started. It will hunt for 30-60 seconds with the variance between the high and low decreasing as time goes on. When I first start it I will sometimes go as high as 1500rpm and then settle down to about 850, then up again but not as high and then back down, this goes on for about a minute or less then it settles out at 860. As winter is now getting closer I am organizing all of the things I want to do this winter and getting rid of this will be at the top of the list. So, what would be a logical sequence of things to check to ferret out this issue?

Mine's got the wiggly idle issue too. It's normal. Sometimes it gets the 2000 tantrum.

And if it rains... images.jpg 72835_1d3e0431ed2a74c5bcf9764c7c88397c_thumb.jpg mine goes nuts for a few days.
 
Finally, after 5 years it is starting to act normal!!! :D

Well, this winter is coming quick, I am doing valves, and will do all the other maintenance required around 20K miles, I'll see what happens.
