My '02 silverado has a rough idle when started on a cold morning. The check engine light has come on and at times the truck dies out. It idles at 500 rpm? When I idle it to 2000 rpms until the engine warms up, then it runs alright, and after awhile the check engine light cuts off. Can you help?

What you first need to do is determine what is causing the check engine light to come on. What I recommend is having the computer scanned at a nationally recognized parts store. Most will do it for free. With the trouble code they get, we will know why the light is coming on and why it is giving you trouble.

Have that done and let me know what you find.
