Thank you Diane and Jody, there was a lot going on at the tuning event. John and I had the valve covers off when whe installed the injectors prior to the event. I will pull the driver side and check the connections tomorrow.
reference says Cylinder 1 is the culprit. Might have a hard time finding it under the driver's side valve cover.........
