No to the alt. The lights will dim if the engine RPM's drop low due to the hesitation. If the check engine light has come on, have the computer scanned to identify trouble codes. Most parts stores will do it for free. Next, if there is no light, check for vacuum leaks on and around the engine. Finally, there are many things that can cause this type of problem. Without a check engine light, it becomes a guessing game. A vacuum leak is a common cause. Other than that, it could be a sensor, fuel pressure issue, dirty injectors.
