In and of itself, a "bad" alternator will not effect the engine performance.
That said, IF the alternator is not properly charging the battery, and the BATTERY capacity gets low enough, then the very low power can result in very low spark production at the spark plugs, which will fail to dependably ignite the fuel, AND THEN result in "rough," or no running.
So, a "bad" battery itself does not cause rough running, but can lead to battery depletion which can.

Should i Replace my dodge Dakota alternator with 90 amps or 120 amps?
If your Dodge Dakota originally came with a 90-amp alternator, it is safe to replace it with the same amperage model. However, if you have added aftermarket electrical accessories that require more power, upgrading to a 120-amp alternator would be beneficial. Make sure that the higher amperage alternator is compatible with your vehicle's electrical system.
