Thanks guys, all comments made have merit. I think I will do another pressure test tomorrow afternoon. I did see the Bentley recommendation to check at temps below 68 and we are supposed to be in the 50's tomorrow. I will use my IR temperature gun to read the temp at the WUR. (I based my 1st temp info on the thermometer in my garage and I am not sure of the accuracy) I just attempted another cold start with the mixture richened a little more and the symptoms remained the same. I will return the 3mm screw back to the original spot as that simple test did not improve the symptoms. My WUR is a remanufactured unit from Flowtech and has a 1 year warranty. If my cold control # is out of spec when I do my test tomorrow I can send it back to them for calibration. I am sure I can live with issue as it acts perfect on the second start, but I am finally getting this car dialed in and I know it did not behave that way off the showroom floor. I will post the new cold control results tomorrow evening.
