Fuel pressure question

Fuel pressure question
I've been dealing with a rough idle and intermittent hard starts . So I did a fuel pressure test KOEO 60 psi, idle 56ish i let it sit for an hour and it never dropped lower then 54 . I turned it on again and gave it some gas and it bogged down and the fuel pressure dropped to 42 . My question is what would cause that to happen . Its a 94 4x4 with a W engine

Sounds like the fuel pressure results are within spec. I don't think there's really a number for when the engine is running, because so many other factors can change it.
How about your ignition? Time for a tune up, maybe? That can cause a rough idle, too.
