We have a 1997 gmc sierra 4x4 truck and we recently replaced the egr valve and it has been running fine. Now the check engine light is on again and we are completely unable to start it in the mornings when it is cold. In the afternoons, I can go out there and it start right up, no problem. It seems to be a "cold" issue that we are having. Can you give me any advice on this?
Thanks guys. I'm so glad I found your site!
