92 eurpean FD R1
it's nearly 2 months now, when i start up the car the revs go to 2K more or less
i remember them to go to 3K or a bit more for a few secs (that's AWS i think)
and more: after that the revs stabilize to 1100 or so and the engine vibrates a bit until it is completely warmed up (a few minutes, but this has always been so, i always wondered if that is normal)

any suggestion?

I have an 89 GTU N/A. To use the AWS the car has to be
started in neutral & left in neutral, and the engine has to be cold. The RPMs start out at 3300 and slowly come
down to normal 750 in about three stages. I don't have any
Engine vibrations.

Iknow that
but it still doesn't work!
by the way the engine starts and runs fine
any suggestion for those vibrations?
they go away as soon as i drive around and the engine warms up
