High temp low oil pressure light comes on after driving for a few minutes, then off when engine at driving rpm. At stop light (idle or low rpm) light comes back on. Normal driving it goes out.


You need to find out why you have low oil pressure. It is normal that as engine rpm's increase, the oil pressure will rise- the oil pump is moving oil faster. Even though your light goes out, you could still have critically low oil pressure. There should be sufficient pressure at idle to keep the light off. The light will come on when your oil pressure is almost nil- I believe for some it's as low as 8 psi. Normally, oil pressure at idle is specified anywhere from 15 to 40 psi. You would have to check specifications for your Expedition. To verify oil pressure, hook up a mechanical gauge at the oil pressure sending unit on the engine block. Check with a local shop.

The causes run from easy, simple to budget busting ruin. Low oil level, wrong grade oil, real old oil, oil leaks, internal oil leaks, worn oil pump, worn crankshaft bearings. It was pretty common on older very high mileage cars to have a fluttering oil light at stops and idle. It was time for a rebuild, or time to look for another car.

Which sensor?


I doubt it is a sensor because a faulty sensor would turn on the check engine light. I would look at fuel pressure in case the problem is a weak fuel pump or pump relay.

Is it my fuel pump???? Sorry will post a vid soon but the description is exactly what it does...


Locate the fuel pressure regulator and remove the vacuum line and start the engine, inspect, if vac port leaks fuel , replace regulator, provided your vehicle is equipped with a vacuum operated fuel pressure regulator.

2004 Ford Focus LX, was sputtering while driving


A flashing light is BAD. Its damaging the cat converter. I would check or replace the spark plug wires ( if all OK, then) replace the coil pack. I would not replace anything unless they test bad. but these car are known for bad coil packs.

2004 Ford Freestar SEL sputtering, check engine light flickering.


Engine lamp will come on if idle is too low / fuel mixture is too lean or too rich.
A faulty spark plug will cause this also.

Van sputters still and worse then before


I would recommend having the TPS sensor checked as that is the first cause for rough idles and stalls...
