1988 900T 16V Cold Idle Issue. Help!

Let me preface my question with an assurance that I have indeed reviewed all old postings and threads on this subject.
Issue: Idle jumps between 1200 rpm and stalling on cold start. Car runs perfectly when warm. This just started happening about three weeks ago. Idled perfect before that.
Action taken to date (unsuccessful):
new AMM (also have tried a known good AMM)
new AIC (also have tried a known good AIC)
ECT checked and compaired against know good one
thorough and complete check for any vacuum leaks
all settings and timing checked and adjusted
new distributor cap and rotor
new plug wires
all electrical grounds cleaned
fuel regulator checked.
The saab dealer (I have a good, trustworthy dealer in my area) has had their most experienced C900 tech working on this for three days and they are completely stumped. They have spent hours checking everything (and are only charging minimal time due to lack of success)and there is no improvement in the cold idle problem.
Any ideas? Recommendations?
Thanks for any help.
Matt
