Question about Cars & Trucks
The code I am concerned with is the random cylinder misfire code you said it has, that is more than likely a possible lean fuel condition, what must be done is to have the engine hooked up to a fuel pressure monitor and watch the fuel pressure when the engine stalls out, if the stall coincides with the engine stall the electric fuel pump may be defective. If the pump proves not to be the problem then you must have the car hooked up to a flight recorder, this is a special tool/device the dealer has that can monitor the electronics that run the engine and if and when the engine stalls they can go back to the shop and a trained technican can read all the engine related data and see what is causing the stall, this can be anything from a defective engine wiring harness to a defective Powertrain control module(PCM). There is no cut and dry answer to this problem, it is a series of tests, most of which will require a trip to the dealer to have done. You have replaced allot of parts, for what reasons you don't say, but if you where just guessing that these parts may cure the stall that was a huge waste of your money and time. PLease keep in mind that the problem must be confirmed to have any hope of repairing it.
