Engine Mechanical problem
1989 Ford Bronco V8 Four Wheel Drive Automatic 127000 miles
After warming up, at idle in drive, (around 600RPM) the oil pressure gauge jerks lower and lower towards no pressure. Each time the gauge hits the red zone, the red "Engine" light comes on. Shifting into neutral or lightly pressing the accelerator to get the RPM up to 700 or so brings the gauge back to normal and solid. If the pressure is allowed to go to 0, the engine will stall. Starts right back up again. Truck is well maintained. Runs very well until this starts. Any ideas? Been running Mobil 1 5W-30 in it for about 10,000 miles. This problem just started. Truck recently had new water pump, intake manifold gasket, valve cover gaskets, timing chain, external fuel pump, relay, and fuel filter replaced. Thanks!
have the same problem?
