    High engine idle speed

    Hi all!
    Own car SAAB 9-3 SS Vector, manufactured in 2003, 175 HP, petrol, turbo, VIN: YS3FF49S931006021, with 5 speed АТМ.
    My mechanic put software Т8 from SAAB 9-3 SS AERO with a manual gearbox.
    I immediately felt the difference, because now the car should have 210 horsepower.
    There is only one problem. Idle the engine is higher , about 900-950 rpm. Whether the gear selector in position D or P or N.
    Could this be due to a mechanical problem? For example, a valve? Is there a difference between Trionic8 software for cars with automatic and manual transmission?
    Can anyone point me where to look for the problem?
    I would be grateful for any feedback and support.
    Please help me!
    Thanks in advance!

    Have you checked your vacuum lines? Could be a cracked or broken line that is causing the high idle speed.

    I want to ask is there any difference in hardware between 2.0t and 2.0T?
    Or is it just the software? Is there a difference as to turbochargers?
    Thanks in advance!

    I'm not sure on where a vacuum line scheme is. On my 1996 there is one right in the engine bay. It's a yellow sticker right near the radiator.

    Also, I'm not sure on the differences of the engines. Hopefully someone will be able to chime in.
