I did think about vapor lock so I did get out and open the gas cap. I did not hear or feel a vacuum as I unscrewed the cap. I actually expected a bit of that and was surprised when it did not happen. I will check out your troubleshooting guide. Thank you. I will also watch the tach when I get back to do more work on the car. I am pretty good with most cars but this Alfa is a different animal so I really appreciate the guidance.
