Ok, I took it to a Chevy dealership yesterday, and they checked everything out. They checked all the grounds, made sure they were clean, charging system, etc. They said everything is fine. They said that this is normal, as the flicker or surge is not that bad. They also said, some vehicles are like this, depending on the rpms, when they go up or down. They said it's up to me if I want to replace the alternator, since the regulator is inside. But, they don't recommend me do that for now. Since everything checks out fine.
