    there are more likely suspects tbh of causing loss of power than the injectors.

    what engine code is this? 1z? ahu? afn?

    check all the vacuum supply pipes for the vnt (turbo variable vane system) they rub thru on each other as they pass around the airbox and down to the soleniod valve on the o/s/f of the engine.
    check the vnt is not seized up either. and the vac soleniod is working. clicking and switching vac and holding it. youd need an engine running diagnositc actuator test done at a garage or using vagcom to do this tho.
    also....
    airmass under reading?
    needle motion sensor in the 3rd injector?

    lots of possibles before jumping on the injectors as a fault. (the old style injectors on these engines being very reliable things.)
