You may have read the previous posts about the truck running rough not firing on all cylinders etc. I finally had to take it to a shop to finish fixing it. I had taken it to the dealer to get it checked and they told me the IDM and the #4 injector was bad. I replaced the IDM and had a shop do the injector. They also added the UVC harness. They said it was melted in a spot and that is probably what took out the IDM. I didn't see it when I inspected it, but then I didn't remove everything to look.

Anyway, got the injector replaced and the truck is in tip top condition. $900.50 at the shop plus the $249 for the IDM.

 

Glad to here you are up and running again.
