Check out your battery/ charging system.
Low battery voltage can cause system faults to appear in the diagnostic system also could explain your lack of power and stalling.

1999 Isuzu trooper oil gauge jumping on and off and lose of power when it is happening


check the connection/wires on the oil pressure sensor
this unit reports a loss of oil pressure to the ECM which will turn off the engine
a faulty connection makes it report intermittently
all this if you have no unusual noises from the engine

I have a 01dodge RAM 1500 and the oil gauge keeps going from 40 to 0 and the check gauges light keeps coming on but I checked the oil and it's fine, what could be the reason for this


1. You need to have an independent oil pressure gauge hooked up to the engine to check the oil pressures at various RPMs and to verify the 40 to zero drop. This will eliminate any issue with the pressure gauge or the sending unit.

2. The oil pressure variation can be caused by an intermittent blockage in the oil pick up or an intermittent sticking oil pressure relief valve. I would possibly suspect the latter if you are getting good pressure and it is intermittently dropping to zero and going back up again..
If you or previous owners have not maintained the engine with frequent oil changes you will get a sludge build up problem in the engine and this will be evident by just dropping the engine sump.

3. If you have had a check engine light warning then you need to have the vehicle scanned to see what fault codes have been generated by the computer. There will be some related to the intermittent loss of oil pressure but there may be others also..

4. You need to have the oil pressure problem checked out immediately. Running the engine when you constantly lose oil pressure intermittently will definitely cause engine damage due to a loss of both lubrication and oil cooling to critical components.

Check engine oil pressure light coming on and causing engine to die. After 5 minutes, no light and no engine trouble.


Yes I would say the oil pressure switch is faulty. The oil pressure gauge uses a different sensor, so if the gauge did not drop but the warning light came on, I would have the warning light switch checked. If the warning light comes on, the fuel pump will stop getting power and you will lose fuel pressure too.

WARNING MESSAGE sTOP: OIL PRESSURE ...wHAT IS


Check your oil, it may be low if not the oil pressure needs checked. The sending switch could be bad or you have low oil pressure. If you have low oil pressure have it fixed ASAP. The loss of oil pressure can cause severe engine damage.

Have a 2004 dodge after engine runs for a while,car stalls and loses powerand regains and losses power, turn engine 0ff for a minute , engines runs good for while and acts the same way.


Check for any vacuum leaks. If possible, have fuel pressure tested and have a compression test done to determine if there is a faulty gasket.

On my display "POWER STEERING" warning flashes then stays. When this happens my car will **** as if it is about to die. Could it be a transmission problem or a cpu problem?


Not familiar with a "power steering" warning.

I think this is similar to a oil pressure light coming on. What you are seeing is that the car is trying to stall, so the loss of power causes the power steering pump pressure to drop, and thus the warning.

Need to understand the underlying issues:

(1) Since you start with a power steering warning, must ask, are you making a short turn when this occurs?
(2) If not turning, then need to understand what you are doing when car tries to stall: Driving at highway speeds, idle, car hot/cold?

Could be a CPU problem, less likely a transmission problem, but on a 2005, should be getting a check engine light.

Afer being driven 5-7 miljes my 99 tauras loses


I would have to say your engine is probably shot. The bearings are probably gone. It is possible, i suppose, that your oil pump is faulty. As soon as the oil warms up, and becomes thin, the rods and lifters start to rattle. The same goes for the oil pump, as oil becomes hot, and thin, it may not be pumping properly. I would try a used oil pump, and see if there is any difference before i wrote the engine off.
