My 98 did that (and still does). My solution was to let it warm up a little (1 min). You can tell its ready from the engine note (it won't run rough), and from the rpms, as they dip to 750 when ready.
Besides, i do that anyway every time I turn it on. Just a little warmup helps getting the oil to flow throughout the whole system.
