misfire 88 GL Wagon misfiring after alternator replacement

[Nevada]

I replaced my alternator and now it's misfiring, does the alternator change the timing at all? 

[moosens]

That should not affect timing. 
 

You’re sure you have an identical match on the alternator ? 

Coil may be loosing its life.

Alternator has no relation to timing...  and changing timing doesn't usually cause misfires anyway.

Check for damaged vacuum hoses, loose wires, damaged/worn spark plug wires, etc, that may have happened during alternator replacement.
