Your alternator wont cause the car to misfire. If you want to test your alternator... start the car, set the brake, pull the NEGATIVE battery cable off the battery. If it dies, your alternator is bad, if it stays running the alternator is good.

You dont want a POWER cable (the red one from the ALT to the battery) being loose and chance hitting a ground... its called common sense.

The car will only die if the alt is bad.

Ok so a bad alt can cause a misfire (learn something new).

Well Juan Morales: This what I would do to test youre alternator, Go buy one of those $20 digital multi Meter, You will get the correct reading on how many volts is running through youre system, I am pretty sure youre mis fire could be due For a tune up plugs wires, Could need a new coil pack, Wiring is loose or damaged on the coils wire harness.

GoodLuck

Agreed,
Or also a clogged injector/ bad injector. The alt is not a case for misifring cause it deals with the charging system only. A power stumble is not the same as a misfire.

Here is a link explaining why it is not a good idea to disconnect the battery with the engine running
