Radiator replaced thanks to Tommy @ Driven Concepts. Took to car out for a drive, got on it some and then some and some more and NO problems with car. I don't want to bet my life on it, but at the moment I would have to say it was the coolant temp sensor having a bad connection. Cleaned up the plug, plugged it back and no problem as of yet. Fingers crossed.....If this was the problem, I can't believe that the coolant temp sensor not making good contact would cause the car to run as bad as it did. Only time will tell....

And to think Epstein suggested this in post #2......Should have checked into this better
