Hey Bill,
This is (or was) a fuel problem. Hooked the battery up yesterday & no codes. Reconnected the door switch, she started right up and ran perfectly. Doubt that had anything to do with it, but will check later when I put the dash back together. Went for a test drive and all is well. No codes. I had not figured the OBD out until now, but if I get a check engine light again, will check it. I now realize that the Bentley manual for the 240 series also covers this engine. That is a relief.

It appears that the solution of plugging the vacuum line to the servo for the recirc/outside air flapper servo fixes the AC problem.

This car is in near perfect condition and all I have done so far is the usual changing of all fluids, belts, brakes and shocks, plus checking plugs, etc. and replacing some vacuum lines. Is this going to be one of those impossible to diagnose intermittent problems? Any hints as to what would cause this loss of idle control and what looked like fuel starving would be appreciated.

Bob
