Car Seems To Lose Power When Accelerating And Feels Like It’s Going To Cut Off

2005 Chevrolet Malibu Maxx LS V6 Just had new plugs, new serpentine belt, new front brakes and rotors, oil change, new air filter, sway bars, and an exhaust leak fixed. The day after having all of this done, the car seems to have trouble speeding up. It doesn’t do it all the time, just occasionally. It happened today while trying to go up a hill. It kind of jerked and chugged chugged and then finally caught speed and power. It also mostly does it when entering the freeway. I didn’t have the plug wires replaced, but I’m thinking maybe i should have? I have no idea what is going on and need to get this fixed asap. Please help. I can’t be driving around with my kid and have the car cause an accident.
Check engine light has not come on. My mechanic that I have dealt with for years did all of the work. This problem only started after my most recent fill up at the gas station. I am starting to believe I may have gotten some bad fuel. This happened to me once before when I had a trans-am. The problem isn’t consistent, only occasional. I put some additive into the gas tank directly. I can’t remember what it was, something to clean the carbon and whatnot. I am hoping that when I refill my tank later today (at a different station nonetheless), the problem will be solved. If not, I will be definitely taking it somewhere to get a diagnostic check run.
