Good suggestions. Thanks! I'll dig in further. I didn't realize ECU could detect or would alert me of prolonged slight temp drop due to stuck open t-stat. Should have known, Saabs are pretty smart. Heater Bypass was changed a month ago due to bypass side leak but temp sensor looked much more involved from WIS instructions so I was saving that and t-stat for a rainy day. Problem has not happened in a few weeks and last night P0455 came on and gage dropped within 10 minutes of driving. Cleared it when I got home, and same today. CEL on then temp drop but not to "zero" since it was off the pin.
Appreciate the thoughts, I'll keep at it.
