Engine stalling

[Haithaamm]

Got a vz ute... recently had idling issues and poor throttle response. Took it to a mechanic and said that the throttle body and pedal needed replacement as they are not in sync..a after replacing them the issue has not gone and if anything worse... sparm plugs have just been changed as well as the o2 sensors... after the o2 sensors have been replaced the car starts for a few seconds normally and then seems to misfire and stalls.
Plugged in a obd2 scan tool and it brings up the code p0336

Looks like your symptoms, I would try changing the Crankshaft Position Sensor:
P0336 Crankshaft Position Sensor A Circuit Range/Performance
