    Stats -
    2013 Prius V
    245K
    Head gasket HAD BEEN REPLACED at @ 230K
    Car was running fine when receiving EGR CEL, no issues.
    Car still ran fine after receiving EGR CEL.
    Immediately ordered New EGR Valve.
    Replaced-
    EGR Valve and PCV Valve
    Cleaned-
    EGR pipe
    EGR cooler (NASTY)
    Intake Manifold

    Started car back up and got the death shake, it would not go away.
    When I put the car in neutral when running it definitely reduces the shake, but still not running well
    P0300 P0301 P0302 codes (received at different intervals of diagnosing).
    Checked Spark plugs and coils, not fouled/working improperly.

    I think I have a Vacuum leak issue (forgot to put a hose on or incorrectly)
    I want to get some feedback before I tear it down for the third time.

    Thanks!

    Check codes and double-check your vacuum hose replacement.

    Is this right:

    head gasket replaced at 230k miles, but EGR not touched, and likely never cleaned.

    EGR cleaned at 145k miles.

    If so, my guess: head gasket blew again, due to the 15k lag of EGR cleaning.
