Question about 2002 Jeep Grand Cherokee
On my 99 Grand Cherokee Limited small V8, the oil pressure is fine at idle and goes to zero with engine revs or at highway speeds. Check gauge lite comes on and beeps. Let up on gas and pressure comes back. Replaced sensor. Shop gauge shows pressure fine. Mechanic gave up.
How many miles are on the vehicle this usually happens when the oi; pump or engine is wore out.
