Have you changed plugs and wires? Any CEL codes? EGR system may need to be checked,cleaned.

I would also check the 02 sensor.  Sometimes a bad 02 can cause some weirdness.

Also a cracked exhaust mani(usually between #3 and #4) can cause a over rich condition resulting in misfires.

Misfire as in firing at wrong time, or not firing when required?  If is not firing properly when shifting into drive, leave in drive and pull plug wires one at a time to find bad cylinder.  Move injectors and retest to see if problem moved.
