Thanks for the reply. Let me share an observation ot two. When I accelerate the pressure goes to normal but will sometimes drop during the acceleration curve erratically. I'm still leaning towards a bad sender but will read more on the lead you've given me.
Thanks again for the input and I'll post updates. By the way the car has only 92,000 miles. Shouldn't have the wear you've alerted me to. I've got my fingers crossed.
