Hi
Your problem is well known.
i recognize 4 origins for your problem:

1. Dirty Lambda-Sound sends wrong data to the motronic, so the sound is damaged and has to be changed.

2. Dirty or damaged non-load adjuster (don´t know the right english explanation but its a motor which controls the stall)

3. Dirty or damaged airflowmessurement (its a plug which is fixed with two screws and a cable leading to it. It´s located in the Air-Intake Complex near to the Airfilter.

4 Sparkplugs wet, dirty, damaged

Dirty or damaged non-load adjuster (don´t know the right english explanation

Should be 'idle-actuator'... very likely that it causes your probs.
