My car just recently started to stall when, I either make right turns or come to a complete stop. I also notice when I am driving the car stutters from time to time especially when at speeds greater than 50. The car starts to jerk like its about to cut off or like the transmission is about to give out. I sent it to the shop to see if the problem could be found at first I thought it was the ignition module because for a while after I got the car back it it was not doing it. I just want to find out the issue because i'am really sick of spending money on a recurring problem

Lack of acceleration, chugging, hesitating, jerking, bogging, misfiring etc. Could be caused by one of the following below:

Oxygen sensor.
Catalytic converter.
Fuel injectors dirty/sticking.
Mass airflow sensor/Airflow meter.
Throttle position sensor.
Crankshaft position sensor
Knock sensor
Manifold absolute pressure sensor.
EGR Valve
Fuel pressure regulator leaking or defective fuel pump.
False air leakage.
Fuel contamination.
Foul/defective spark plugs.
Open spark plug wires.
Ignition coil/Coil packs defective.
Incorrect ignition timing.
Cap and rotor.

Note:If it doesn't apply disregard it.
