2005 6.0l rough start
My truck most of the time is really rough start. It turns over perfectly fine and then fires up but at really low rpm and then will catch back up to idle eventually. It drives normal. Sometimes rough start. Sometimes starts fine. Sometimes won't start at all. We have had rebuild ficm, changed ficm relay, new throttle response sensor. Only code that pops up on my mini maxx is P0487 egr throttle control curcuit. Can anybody help?

I had a friend go through this very same thing, come to find out, he had a few injectors that were on there way out. Truck ran great when it was warm but had rough starts and ran rough when it was cold. Installed new injectors and the problem was gone.
