This may very well be a fuel related issue. As you know you have replaced many of the components that control spark. Since the car continues to run (even if badly), you know there is not a spark problem at this point. I would recommend checking and replacing or cleaning the mass air flow sensor. When this is faulty or dirty, this can cause intermittent stalling since it helps to control air/fuel mixture to the motor. If you would like assistance replacing your mass airflow sensor a certified technician from YourMechanic can come to your home or office and complete this repair.
