    1- clean Intake minifold (clean the current one)
    2- clean EGR valve cooler (clean the current one)
    3- new sparks plugs
    4- clean fuel injectors ( new o ring and gaskets)
    5- pvc valve new (new)
    6- clean the throttle body only with the cleaner
    after all the car running a lot smother than before of course yes

    BUT the checking came back again after one day.

    If you have a really rough start with shaking and a severe rattling, plus it goes away and runs smooth for the rest of the day, it is very likely a leaking head gasket. Very common.

    It does not present in a traditional way on a hybrid.
