    Hello and thank you for reading.
    My 2018 2.7L 4 cylinderTacoma makes this weird noise after a long high pitch sound. Only happens on a cold start. The high pitch sounds appears to come from a air pump component but then the noise come as pressure being release but I am not sure if this is normal or just my anxiety that something is wrong with my beloved.

    Check the video and watch until the end for accurate description.
