I have a 2008 Dodge Dakota 4x4 Pick-up.

Hello, no, there is nothing that needs to be reset with the work you performed. The only thing related I can imagine is that if something else got damage from being soaked by coolant. But even then, you would find clues via diagnostic trouble codes that would be set due to some kind of failed wiring, sensor or connector. When you tell me that a tech is struggling to find out what is wrong with your vehicle -- when the failure is actively occurring -- it makes me feel like you need to take it to a different shop or speak to the manager of the current shop for some clarity and further guidance. A failed battery will typically not care a stalling situation. And the engine's processor does not communicate with a battery. Low battery voltage may cause trouble codes to be set. And, the battery may have been needed. But I do not think it is part of your concern of stalling.

Despite what some people may tell you - dealerships aren’t aren’t necessarily the best option for your vehicles repair needs. You simply need a knowledgeable mechanic to fix your truck - likely found at local independent auto repair facility.
