PSD Idle Problems
I own a 1996 F-350 PSD dually with 135,000 miles on it. Engine is stock and runs great, except for a frequent idling problem. When the engine is at operating temperature, I experience frequently recurring rough idle for about 5-8 seconds before it levels off to a smooth idle. I almost sense it could be a malfunctioning injector pump. It sort of reminds me of an gas V8 running on six or seven cylinders for a little bit...
Any thoughts for me?
Thanks

2 things I would check before replacing anything:
1. Is the fuel regulator screen clean? The screen can be reached from the inside of the fuel bowl. Take off the cover to the fuel bowl and there should be a hole on the top right. Take a Q-tip and gently reach in and clean the screen.
2. Test the fuel pressure. There's a valve on the FPR.
