Stutters when giving gas/selecting D or R at cold start Topic is solved

[Woolf75]

Ok, so the same problem is back, it went away for some weeks (I actually didn't drive the car so much). I thought I had magically cured it by replacing ABS module (which had to be replaced anyway). Again...
Cold start => idling fine, no stuttering => select D or R => engine revs drop, almost dies, POWER BRAKE (brake servo..?) disappears => select P => back to good idling.

After 30 sec or so, car is driveable.

Is there an overview/schema over the vacuum hoses somewhere to be found?

Oh. And could these symptoms appear when having leaks in exhaust system?

There should be a vacuum hose diagram under hood. It does have all the trappings of a major vacuum leak.
