The car gets past 200f and the oil gage jumps bettween 40-80psi and off sets the idle I checked the oil and its full .I was just about to give it a oil change but i wanted to look further into the problem so i checked inside the vavle cover oil filler hole to see that oil isnt flowing while it was running? then further took the dis off to find its mostly dry im guessing its the oil pump?
