High engine idle speed

[bobimihi]

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.

Thank you for your prompt response Shazam!
Where can I see vacuum lines scheme?

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.
