What would be an appropriate amount of labor time for a dealer to charge for this? It is hard for me to imagine it being more than 1 to 1.5.

They spent 2 on diagnosis when I told them when I dropped it off that this was one of my two most likely suspects (thanks to this board).

Thanks -- maybe someone has an alldata or other book.
