Its been a while since I have been on the sight, But I have a question for the GURUS..... When its cold out and the truck idles for a while, the idle kicksup on the truck?........ when I jump back in and tap the brakes it will return to a normal idle ..... What gives?... Is this normal and what is the reason? It will also kick back on if I continue to let her idle. It only does it when its in the 30s, or lower.
