Car stumbles or dies under load
I noticed this problem the other day, I turned the radio, defrost, headlights, and wipers on and noticed my dash lights started to dim. Then going down the highway it acted like it was gonna die. So I press on the accelerator and it ran fine the rest of the way home. Well I took it to autozone and they said the battery and alternator were both good. So now I'm back to square 1. And I'm not sure what else to look at.
