Heh...and for CIS it behaves well...I sometimes have some cold start
hesitation, other than that, cleanest burning car i think I have ever
owned.  My hesitation only happens when its around 50 degrees or so...its
like the thermotime kicks off too early and the car isn't quite warm
enough for how lean it goes...oh well.

Ok, make sure of that.  The CPRs are different part numbers for the lambda
and non lambda cars, would need to check the bentley, but I wouldn't be
surprised if they operate in different ranges.

Ok, what I would REALLY be curious of, is what happens to control pressure
at the time of the problem.  That would be a definitive test as to it
being an issue with the CPR or not.

Entirely possible.  Setting mixture to correct settings (with an exhaust
gas analyzer since you have no lambda) should be the 1st step.

Let us know how it goes Cathy!
