Default Missfire...

Well onto yet another issue, just one after another with this thing lately.

She's a 98 12 valve, auto, built trans, 50hp injectors, plate, intake and exhaust.

At 1300 rpm it's got a miss/stumble, nothing higher nothing lower, idles pretty good.

What should I be checking?

Fuel pressure, idle and at 1300, fuel quality, timing, compression test & injector pop pressures (last)
Been serviced correctly? Might also check lash and make adjustments.
