Getting these codes, rough idle, snap on engine analyzer shows all four(4) with no readings, but getting voltage.

I attached the test that we need to run through for this code but given you have misfires on two cylinders, I would bet we have injector issues.

I attached the testing below so let's at least run through the system inspection items and go from there but again, I am thinking injector issues so you may want to swap those injectors with the cylinders that are not missing and see if the misfires move.

Let me know what questions you have on this. Thanks
