OK folks. Here's what I got. 06 F250 6.0l. about 120K miles. Only mods are EGR delete done about 2 years ago. The truck all of the sudden started being a little more difficult to start but once running I noticed 2 things happening. 1. If I try to drive the truck while still cold it will shut off when changing from 2nd to 3rd gear and is very difficult to restart. If I wait until the truck warms all the way up to running temp it runs fine. But if I accelerate hard and let off it will shut off as well. So I pulled the codes and it showed low voltage on all injectors so I had the FICM rebuilt and while at it I changed the fuel filters just in case. So now I am getting no codes but its still shutting off on me. Oh and it has good fuel pressure too so pretty sure its not the pump. I don't think the EGR delete would have anything to do with this but not sure. Injectors maybe? No black smoke from the tail pipe. I did notice a wah, wah, wah, wah sound from the breather though. Any Ideas??????
