Hello, i'm writing from Italy, as i wrote in the presentation i just become owner of a GMC Sierra SLE 5,7V8 from 1989.
We are restoring it and we found the valve in pics, did some one know what is it and where he can feet?? I download the service manual but it is really difficult for me to understand.
When we start up the truck and he is cold , does not run very well and we found the alarm "check engine service", when become warm he run perfectly. Can you help me? did you know if there is some diagnosis instrument?
tks for now and sorry for my english.. for sure it is better than your italian
