Any one here have idle problems with Alfa 156 2.0ts 1997-1999 ?
Read and hear so many opinions about this problem in other forums but now i think i know the remedy.
I'll post it here if it'll be matter.

Mostly a simple problem.
The butterfly valve in the inlet gets a ridge of dirt built op on the circumference of the housing.
Then the valve doesn't close properly anymore and the electronics keep correcting based on the informations received.
Just simply take the 2 hose clamps off, remove the hoes, clean the internal and mount everything again.

If this does not work try also cleaning your becks by ultrasonic.
