    Hello!
    The problem with Toyota 2.0 d4d check is not lit, the most noticeable is on a warm engine, at 2000,000 rpm, e.g. at 3rd or 4th gear, the car loses power, the turbine after regeneration is about 1500 km, I cleaned the EGR valve, nothing helped, I unplugged the flow meter, nothing it helped, while driving, when he has such a mule, you can hear the whistle of the turbine, but with the removal of gas, the whistle decreases. I do not know what to do next, whether to clean the catalytic converter or to typically replace the SCV.
    maybe someone had similar symptoms, I would be very grateful for advice.

    You checked the tightness of the boost system, the pressure. It could be a fuel pressure problem as well as a boost pressure problem. When the car gets weaker it smokes. There can be a dozen faults and the effect is the same ... First, a computer and reading errors and parameters, then some logical diagnosis.

    The only positive reaction occurs after thorough cleaning of the flow meter, the car comes back to life and works perfectly.

    After connecting the computer, there are errors:
    P0100
    P1115
    P1228

    I am afraid of error P1228 the most, is it possible that the SCV saucers are damaged? could the car only occasionally catch a bug?

    EDIT:
    The reason was the SCV valves after replacing the car like new.
