I don't see how cleaning the airflow plate with rubbing alcohol would make any difference. When this plate sticks, it means that it misadjusted and rubs against the throttle body.
Rodney: Before you replace any hoses, ask your mechanic if he thinks a quick check for a vacuum leak might help. However, a vacuum leak shows up as rough idle. If you don't have that, it sounds to me a matter of timing, idle speed, and mixture.
Is the retard on the distributor connected and working?
Can you let the mechanic confirm that the set-up (Vacuum lines) is unmolested and strictly stock?
On these engines, there are so many vacuum lines; add to the above the brake booster (Servo) line coming from the TB and going to the front.

Gunter,
I have a '88 930, stock CIS system, although my idle is hit or miss, sometimes its smooth as a babys bottom, other times it is rough as helterskelter and starts to hunt for a couple seconds. I know that means Im running rich, but I need to keep it rich otherwise if I try leaning my CO out, the car runs really rough. Could this mean I have a vac leak somewhere? Also you stated that the Brake booster(servo) line comes from the TB andgoes out to the front, well my brake pedal feel too soft and now pushes all but just 2" from the floor!
This all happened when I came down to AZ from Chicago just yesterday for my job.
any ideas?
Eddie
