    Strong vibration and noise for a few minutes coming from the front passenger side, happens when the engine is turned on in the morning. A couple of hours later same thing whenever the engine quicks back on.
    Also, loss of power when using the power mode.
    2015 PiP, around 102k miles.
    Please help.

    No.
    But your diagnosis makes a lot of sense. Looking up, the intake manifold, cooler, and PCV valve can be also compromised and may need cleaning/replacement, let's see their condition when I take them out. Very useful video here:

    Thank you bisco!
