I'm guessing when the engine light comes on, the computer is going into a default mode -- enough to keep the engine running, but not efficiently or with power. You need to get the error codes checked to determine what is going bad. It may be a throttle position sensor (TPS), or a crank or cam position sensor, which feed critical information to the computer.

Do you have a Check engine light? Has the fuel pressure been checked it may be low due to a plugged system or a failing fuel pump. Do the scan first.

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.

My 2009 pontiac g6 monitor says engine power reduced , the car sputters , and ut only gos 20mph


Well, I doubt more than one sensor is bad, if any.
The trouble codes tell the mechanic what to test, not replace.
The O2 sensors provide data to the engine computer to adjust fuel mixture. You could also have low fuel pressure or something else.

'Engine power reduced' comes up along with check engine light. Replaced throttle body the other day but it happen again! Anyone know what is going on and what could be causing this?


check engine lights notify problems in 2 areas . firstly the engine and also the transmission.As you state a problem in the transmission it is possible that is the area of concern. A service dealer will be able to tell you exactly what the sensor fault is for that code.

Loss of Power / Over Heating


eeek, sounds like a possible head gasket failure. Check your coolant and oil. If the coolant is low top it off, and if the oil is milky, you are getting coolant in your oil which is usually a bad head gasket.

After driving my car 2006 chevy impala for about 20 miles the dashboard warning light oil pressure low stop engine and the oil warning light appears, but if step on break or slow down it goes out..wha


Verify that the engine has the proper amount of oil. The inertia from accelerating may be moving the oil in the oil pan away from the sensor and causing it to send a signal, then when you slow the oil levels out and the sensor go's off. I've had this happen alot with a taurus that I owned. The simple solution was to top off the oil to the correct level and the sensor did not come on again (until it ran low again, had a leaky oil plug on oil pan).

Check engine light on only can get speed up to 20 mph then powers down in city driving 50 out on open road


Hi
very common fault, its the EGR valve cost new about £130 although you can clean the part and refit it. sometimes that works.

The EGR Is exhaust gas recycler valve, it forces unburnt fumes back into the engine to reburn when they fail, the engine light comes on and while the light is on you will be lucky to get 20mph in low gears and like you say 50 on the open road.

You can clean it with Carb cleaner, they are very easy to remove and refit so worth a try before buying another.

Regards
Dan
