Here's the story... Getting onto the highway yesterday and as I was accelerating (nothing crazy) to merge into traffic, my Check Guages light started to blink and beep and my Oil Pressure Guage dipped to zero. I immediately pulled over and shut off the engine. Checked for leaks and oil level. Everything was fine and the engine felt like it was running normal/well.
So of course I jumped on the forum when I got home and read up on the issue. Most recommended the Oil Pressure Sending Unit which I replaced this morning. Here's the strange part...She has always sat at a constant 40psi until yesterday and now even with the new sending unit she is running around 50psi and fluctuates +/- 15psi.
Most times a bad oil pump shows LOW oil pressure so the only other thing I can think of is an Oil Filter that went bad??
Any thoughts?? THANKS!!!!!!!!!!!!!!!!!!
