I went out and cleaned my IAC the other night after reporting on here that I had a bad idle and getting your suggestions. On the way to work yesterday morning the truck ran fine. I did get a service engine soon light and took it into the dealer and they said it had something to do with the egr and now the lights gone. But I wanted to thank the guys on this board for the quick help to my question and problem.

 

Now clean the EGR valve out. Mine had chunks of carbon in it.

 

Works every time
