You appear to have a bad ignition module.

Did you mean coil the 1994 3.1 did not use a distributor , sounds like a bad coil pack and cylinders #3 and #6 do use the same coil. I would also check 3 and 6 plug wires this system is a waste spark design meaning when # 3 coil fires it is supposed to go through #3 plug wire , through #3 plug ( ground) through the engine block through the #6 plug then through the #6 wire then back to the coil, Then when #6 fires it works the opposite way, so in theory you could have one bad wire affecting 2 cylinders .....

The coil packs are in the following order from top to bottom:
6,3,2,5,4,1.
The firing order is 1,6,5,4,3,2
The cyl numbering is:
2----4----6

1----3----5

For the 1990 Buick LeSabre 3.8L V6:

Firing Order:
1-6-5-4-3-2

Cylinders:
.......(back)
2........4........6
1........3........5
.......(front)

Ignition Coil Connections:

Change the spark plug wires with good replacements, possibly replace the distributor cap.

Crank posistion sensor. It's behind the pulley off the snout of the engine

Ok this may be something smal that may be simple to fixs; your plugs are in the wrong cylinder?

Check Your gap size .060 (In thousandths of an inch)

Im not sure of the size of engine please look below for your make?
