Do the 1uz engines have a Rev limiter while out of gear?

    Hi All

    I’m having an interesting issue with not being able to open
    my throttle while in Park or Neutral!, it won’t Rev over 2700Rpm
    to me this seems very unusual as I’ve never owned a vehicle that’s
    done this before!, So if the throttle is opened and I try to Rev it over
    2700Rpm it’ll Rev to that Rpm then die then Rev up again then die.
    And I’ve also got another 1uz but it doesn’t do this! so I’m wondering why?,
    it Revs normally while driving it but may have the slightest hesitation around
    that Rev range but while not in gear dies at 2700Rpm.
    Both 1uz engines are around the early 90’s I’m guessing.
    Both engines are in Toyota’s my original one that I’ve had for about 15 years is in a
    89 model Hilux 2wd with a manual gearbox and my new 1uz engine is in a 92 Toyota
    4Runner 4wd with a 1uz Automatic gearbox behind it,
    So has anyone got a 1uz that dose this? And Is It NORMAL??
    Any help would be greatly appreciated
    Thanks for your time and help

    Cheers
