hanging idle at 2k, then dropping/dying My T/A has started doing this on its own, used to not do it. I had the car dyno tuned and the tuner just brushed it off I guess? It did it before and after the tune. I'll come to a stop light with the clutch pedal down, and the car will even sometimes go up to 2 grand, hang there, and when I come completely to a stop it will idle down, and usually will die. The car never did this before and even idled great on a stock idle table. car has a 228/230 .579/.581 on a 112+4.
any ideas guys?

If you have a vacuum leak, the idle will be high and uncontrollable.
What you described sounds tune related, most likely from having high values in B4307.
The desired airflow table needs to be logged while driving not just sitting on the dyno.
Is your idle high during cold start?

Idle dropping below desired when you put in the clutch is usually Throttle Follower related. There are a few tables in this area that would effect that. I had a car yesterday with the same problem. The airflow multiplier was the problem on this one.
