When i first start the truck it idles about 1200ish, then drops after a minute or so to about 700. Once its warm and if I am sitting at a light or put it in park it will surge up and down from about 600 up to 750 or 800. Is this normal for these trucks or is something acting up?

Mine hunts around at idle too, and IIRC its common.

I just noticed that you live in Yakima about 45mins from me.. Do you have a syclone or a typhoon?

Re: funky idle

Please let us know the out come of this, I have the same issue. My check engine light will pop up but once you take off or give it a few RPMs it will disappear. The code is 035, can not set RPM? Any guess on next step? It has a full tune up on it using all ACDelco parts?

Re: funky idle

I dont get any codes and the truck seems to be running great. The only oher thing is it seems to only make around 10-12 lbs of boost.
