Engine Keeps Dying at Idle, while Reversing or Accelerating From Drive

Maintenance/Repairs

2011 Buick Regal CXL 2.4 L non turbo. I recently had the Battery, Camshaft Position Sensors, Intake and Exhaust Solenoids, Alternator Belt, Tensioner, and Pulley, and also the Mass Airflow Sensor Replaced because the Check Engine Light was on and the Mechanic who fixed it said this is what all needed replaced. Now my engine idles really heavy when in park, and Jerks forward when in drive with my foot on the brake. Also the car engine will literally turn off and my car will seize during either Reversing, or Turning at low speeds and acts like it has trouble accelerating.The only way to get it to not die is gassing it kind of hard during either of the two situations. Also, my car accelerates itself now just a bit. Say in going 30 MPH down a road, the car will accelerate itself to 35ish and stop. Once up to speed around 40-70 it seems to be fine.

Sidenote: I installed a subwoofer, door speakers and radio back in March 2024, but it’s never made my car lights dim or caused any problems, other than the radio resetting completely once while I was driving, back in July 2024. It is Running 800-1000 watts. I don’t know if that is causing a problem or not, but I thought I would throw on the extra info in cause someone knows something that I am unaware of. When the car died the radio stays on.

Does anyone have any ideas what could be causing the engine to die?
