Engine Mechanical problem
2002 Ford Taurus 6 cyl Two Wheel Drive Automatic 115, 00 miles
I have a 2002 Taurus. When you first start the vehicle it sounds great. Engine is quiet, runs smooth. You can drive it at any speed with no abnormal engine noise. After about 5-8 minutes when car warms up to normal running temperature the engine begins to knock and continues until vehicle is shut off. As long as vehicle is cold I get no abnormal noise. Vehilcle still runs well with no loss of power at all. Do you have any ideas?
