Hesitation at low RPM surges when stopped and in gear

Welcome to 2CarPros.

If the system is over charging, that is a concern because not only can it cause damage to some components, but it can also cause a fire.

Now, the alternator output is regulated by a voltage regulator. When the engine is running, the voltage at the battery should be right around 14 volts. With that in mind, we really need to check if it is over charging.

Here is a link that describes and shows how to check the alternator on your vehicle. Please do this and let me know the results.

The voltage regulator on your vehicle is part of the alternator and isn't serviceable. So, if it is bad, the alternator needs replaced.

If you find the alternator is bad, here is a link that shows in general how one is replaced:
