I know this question has probably been asked a million times and Im hoping for a best guess starting point. It seems like there are a lot of things that cause can cause this. I get a high idle when cold, almost 2k rpm. it does it 90%of the time when i start it which is what is throwing me off. sometimes it wont do it at all. sometimes i can throw a rev or 2 into in after 30 second or so and it will drop to normal. it seems to idle fine after that and for the rest of the time i drive it. Trying to do everything myself on this and learning as i go. Can someone give me a "most common" starting point? If that exists? )
Thanks for your time
Dave
