Carl; thanks for imput. The temperature related theory is correct. Mine also seems to run differently depending on outside temperature not engine temperature. Our problems seem all to similar. I have also found similar problem on Riviera section. And does not sound too encouraging. I first suspected the fuel pump but have been reluctant to spend $300 to find out. Now I dont think that is it based on some of responses to other vehicle problems with same engine config. Problem is now I really dont know what to think. Seems to be alot of people pointing at crank sensor. But they always seem to check out ok with test but have not found where anyone may have replaced the sensor. Please let me know if you find out more. What a nightmare!
