Thanks there Franke!
No; I'm believing that the 'off-idle sag' issue, is DIRECTLY causing the Cruise issue as well - a 2mph swing in speed - any speed, when cruise is engaged. I'm attacking the 'sag' from a different angle, until I get DataMaster navigation down (which may show some Voltage swing on some circuit).
CC diags flow chart for 'loping' cruise (NOT flow chart for total Cruise failure), DOES include a vac leak in CC vac servo lines. Working on vac routing now..........
I may have a vac leak somewhere, causing both CC issue, AND 'off idle sag'. Is Cruise vac supply, and MAP vac supply integrated???
Idle quality is perfect however - no loping.

If there is a vac leak, it is triggered by SOME circuit energized in CLosed Loop, I believe, and even then, I cannot pin it (intermittent)
AND, it may be related to the A4 4L60e tranny Controller Module, or CM wiring ........................
Thinking hard on this now with my 'CPU', and it's smokin' hot - you can tell by the dual ear exhaust

need 'The Patch'
