If you have a smartphone or tablet, there is a cheap app called Forscan, it reads the codes very well. Most tuners won’t read all codes.
Then you need to get an adapter that plugs into the obd port and broadcasts WiFi or Bluetooth depending on your phone.

For around $30 you can be reading detailed info on your truck or any Ford vehicle. It can help pinpoint your problem.

I don't think I would try an oil flush, but the popular stiction reducing additives are no problem to use. Sometimes they work, so it might be worth a try.

Sounds good, I got hot shot in now doesn't seem to be working yet, but I will give it the rest of the 5000 miles I put it on like 100-200 miles after I changed the oil before I put it in. I don't drive it much either put on 5k in 12-18 months. I put in shell 15-40 rotella t4 or 5 whichever is non synthetic. but hear alot of guys saying 5-40 is the way to go. could that have started this problem. Cause it started about same time. I'm going to hold off on the spool valves until I can afford to replace the injectors that way if I screw them up I won't be sold. Thanks as always for all the help

That 15w40 will definitely make the issue more noticeable especially when cold. With the HSS additive you need to take a good road trip to get it hot and mix. You need to find time to drive the truck and put it through the paces. These trucks don’t like to sit.
