Oh no defintely. It was replaced once I found out that I was running without one. I had no idea. The mechanic then inspected it and saw that it was working properly so it was replaced.
Anyway I was just trying to see if the loss in performance is due to it now running the way it should be. I guess that's it.
Talk about failing the emissions test, I failed it three times until the real problem was realized.
