It sounds like, in your case, that the basic mix may be lean and the car needs enrichment from the lambda system to run, or that it's not getting enrichment from the WUR.
Recommend that you check your on/off ratio and control pressure, and make sure that both sides of the WUR are holding vacuum.

Hi Chuck:
Nice to hear from you again. I recall that we were chasing down similar climate control problems a year or so ago -- yours solved by a new CC panel/control unit, and mine by a refurb'd temp regulator.
I do not doubt that there may be something else going on under the hood, but -- to the extent that I can -- I plan to leave "well enough" alone for now. The car seems to be driving as well as it ever has, and goodness knows I'll have other maladies to keep me occupied. There can be no doubt, however, that the OVP was the root of my current woes. If there are underlying issues, I'm sure that all will be revealed in the fullness of time
Thanks
Mike
