2026 F-150 2.7L EcoBoost – Rough idle/vibration right after oil change at 800 miles, worse with AC and battery voltage fluctuating 12-13V while driving. Normal or should I bring it back?

Got the first oil change done at the dealership earlier today at 800 miles, and immediately after, the idle feels rougher than before. It is the same steady vibration as before but I feel like it had a heavier “pulse” vibration added into it. It’s just in park or at stoplights then goes away when I drive. Also, while I’m driving, the voltage jumps back and forth from 12 to 13 volts. Also, the vibration gets worse when I crank the AC

I have a 5 hour drive tomorrow for a vacation so I’m not sure If im just overthinking it. Am I good to drive it tomorrow without worrying of being stuck on the highway?

I had a not so good experience on my last truck so excuse me if this is a dumb question. I freak out about everything in this new truck
