ENGINE STUTTERS

1991 Cadillac Fleetwood

Engine Performance problem
1991 Cadillac Fleetwood V8 Two Wheel Drive Automatic 107700 miles

We have replaced spark plugs, wires, dist. Cap, rotor, and fuel filter. The car runs but has a stutter in it. We have also replaced the oxygen sensor and still nothing. Can anyone help me? Going on 2 days and running out of suggestions. Anyone heard of manifold gasket leak maybe?

Thanks

Is it running rough?
A ck engine light?
What size of motor? 4.9 or 350
is it front wheel drive or rear wheel drive?

It is a 5.0 V8, no check engine light.

We found the problem !

The star wheel inside the distributor, one of the stars was totally gone. Replaced with a new distributor and runs perfect.
