Well back to the belt that broke... I had the oil changed today, but the pressure gauge is still acting funny. The good news is that it is most likely the pressure sensor. When the belt slapped around evidently the shop replaced the oil pressure sensor?
Anyway, I am going to give it some time to see how it reacts. It is moving more than the old one, but it could just be more sensitive? I don't know. I do see a part number S4078, $57.33 on the invoice ouch! I guess that could be the problem or the cure.
