Engine Performance problem
1999 Mercury Tracer 4 cyl Front Wheel Drive Automatic 133000 miles
The oil light comes on when driving.
How can I tell if I have low oil pressure or a faulty light or a faulty switch or a failing oil pump?
I was told by my mechanic that it will take 45 minutes of labor time to hook up the engine and it will cost $45 just to read the oil pressure.
Is there a quick way to determine if I have a failing oil pump or a faulty light/light switch?
Thanks you for your help.
