There is a knock in the engine and the launch reads injector compensation code could these be injectors?
No, a knock is a piston or internal part hitting another part. Take your auto to a repair shop.

Jambo Jambo.This problem, unfortunately is going to be in the fuel injector pump itself. If the veins are wearing it will begin to fail at high RPMs when the fuel demand is high. You are on the right track though. It is fuel. Replace the injector pump and time accordingly. Feel free to contact me if you need anything else.

okay.how would the injectors have anything to do with the vehicle stability control/4wd.??if it were injectors at such a low mileage you would feel a real lack of power.now as toyota own diahatsu you could save yourself a fortune if you ask them to diagnose a fault!!to check vsc is working put car in 2nd and floor the pedal turning as tight a circle you can brave.it should stop the inside wheels from screaming....to check 4wd do the same and you will feel the car trying to pull itself apart.you will see what i mean.!!!
SOURCE: po202 code engine idles rough,
DTC P0202 injector #2 control circuit.
fuel injector operation is monitored when battery voltage is more then 10.4 volts, auto shutdown relay (ASD) is energized, fuel injector pulse width is less then 10 milliseconds and engine speed is less then 3000RPM. DTC maybe stored in power train control module (PCM) when no inductive impulse is sensed after fuel injector turns off with no other fuel injectors turned on.
possible causes are:
defective fuel injector
defective ASD relay circuit
defective PCM
defective connectors or wiring
if you are getting injector pulse, the the PCM and wiring and ASD are ok ( get a noid light and plug into injector wiring plug in crank engine light should flash
if you have a flashing noid light REPLACE INJECTOR

if you can get a good set of used injectors you should change all of them.
