Ok I need some advice about my 7.3. After driving the truck from Joplin to Springfield yesterday the truck seemed to want to die as I pulled into a parking lot. I pushed in the clutch and the truck barely idled. Then out of no where it went to a high idle and then smoothed out. It threw a code but when we plugged in a Pegasus tool to read the truck began idling bad again for just a second or two and we couldn't communicate. Now anytime I spin the motor above 2300 rpm it seems like it has a miss fire or a limiter and doesn't want to pull anymore. But it ran well enough to get us home. Any help would be appreciated. This is my first diesel and my back ground is in mustang. I don't know how else to describe what it is doing. I went ahead and did a fuel filter because I didn't know what could be causing it. While I was there I check fuel pressure with a tire gauge (I know I am a dummy) and it had about 54 psi at idle.
