To me it sounds like speed sensors on pump.
1st thing I do is run them on a scope at ecu then if poor or missing move scope to pump so it eliminates wiring.
I often bump into a rough pin on plug on side of pump.
this gives you symptoms like you're explaining.

Boicult If you dont have a oscilloscope then your screwed.
sorry.
But with me I scope signal inputs at ecu.
thats no fun, look at where the ecu is then you see what I mean.

If theres no signal I scope at pump.
if signal there then it always ends up being a pin in the wiring plug.

I am have the same problem on 97 2.8, perfect idle P & N, perfect when driving. No smoke, even when gunning it. Good in D & R at first, but rough idle when warm. I just replaced fuel filter, new factory part from Mitshi dealer in bury st edmunds, I though this would f/x problem. Old filter was a generic brand. I see that jimmybond seems to be the expert on this issue. Jimmybond, if you see this can you contact me I am local to your area. Thanks, any advice is appreciated.
