200 idle probs

[crisarc]

recent running prob on my 200 with ur 20 3b engine,
on warm up its runs for a bit then conks out, when warm it runs better, but even better with the aux air valve disconnected,
no boost leaks, new white and black pin sensors at the back of the head,
question is does the aav on the motronic have a constant power feed or does it vary?
if so what controls it?
i have also changed the aav, but to no avail, it runs ok with the aav disconnected ,,, but i need to know
oh and today the push rod on the clutch master snapped , in the middle of wolverhampton, had to use the starter to get it going and crash change it home....
oh what a day
