When I start my truck on a cold morning, I have noticed that it idles a little high right of the bat (about 750). then after a couple of minutes, it will kick up to about 1100 rpm. Is this normal for my stock 02'? The only reason I ask is because I plan on getting a Wildman chip, and I notice that it is available with a high idle file.
I guess I'm basically wondering if my stock computer is doing this, or maybe is has some type of aftermarket chip, or download in it???
Any help is appreciated
