another throttle problem
 

Hi guys,
i have a problem.
When i'm driving and push on my cluth the RPM of the car won't fall down as normal or sometimes the RPM even goes higher.
What can cause the problem?
boxster 2700cc
year: 2000

thx in advance

What model do you have?

Rev 'hanging' is common on newer cars to reduce emissions. Otherwise you might want to start by cleaning your throttle body.

i allready cleaned the throttle body


i have a 2,7 from 2000

Have you checked for vacuum leaks around the throttle body?

Any issues with the throttle pedal itself? check the hinge at the bottom hasn't broken.

Any other symptoms, loss of power etc. Any error codes?

i have no power loss. Power is still great.
There are no error codes. (with Delphi)
with vacuum problem the throttle can hang in the same rpm, but can it also go higher in rpm? from 4000rpm to 6500rpm.
When it comes beneath 2000rpm/2500rpm it fall's down normally.
