Surges at start up

[97Crew]

97 with 235,000 on her... The problem is when engine starts she surges, lopes, pulses (don't really know what word to use to describe it) after starting. As soon as I give it throttle for a few seconds it goes away. The only time it happened use to be when i would shut down going through a drive thru so i could hear the person on the speaker. I found that if i put the truck in park instead of neutral this problem would not happen. Now yesterday it did it after being parked for about five minutes and again this morning (hadn't started her since it did it yesterday). I gave the throttle a good whack and then it smoothed out and is warming up like normal. If this is covered in a thread that i couldn't find PLEASE direct me to it.... Any advised will be greatly appreciated!

UPDATE: It is doing it every time I start it now.

maybe oil leaking back down of out the HPOP? Or possibly just the EBPV kicking in. What kind of temps is this happening in?

Ice cold and then normal op temp. Found a thread on drdiesel with the same prob. Ended up. Being bad injector o rings. I'll chk that and letcha know. Thanks for the info

Well it appears this was a fuel problem. I am into my second fresh tank after running some diesel clean through it and went back to Ford's diesel additive (I had started using Optilube), no more lope when i start her up. I also cleaned the screen where the fuel exits the bowl. I'm getting the best mileage ever, even running with a heavy foot.
