You could be looking at a clogged injector, leaking fuel line, gummed-up filter or kaput fuel pump. Fuel pump, fuel filters (there's 2-a bag filter for the fuel pump, and a tank-type filter), fuel pressure regulator, ignition wires, fouled spark plugs, dirty fuel injectors, poor engine compression from wear and tear, clogged catalytic converter...

Peugeot 308 low oil pressure and loss some power


Low oil pressure starts from oil pump sounds like its blocked either in the pump filter or galleries in the enging. I would first call the dealer and check what filter system is on the pump which may require removal of the sump to replace or clean.

I would certainly not use a car with this problem as it could well cause engine failure. Try a good quality flush first and run the car for 20 minutes minimum on tick over. Remove and put a good quality oil in and do another oil change again if required a month later with a flush to make sure the gunge is out.

If this does not help do an oil pressure test and see what it comes out at checking the manufacturers recommended pressures. If you have changed the oil, pump filters and done a second oil change and still get low pressure then you may well have a faulty pump.

I would also check the oil pressure switch to make sure it s not giving a false reading. The loss of power sounds like Turbo failure and again dirty oil to the Turbo oil feed pipes could be restricitng flow, hence why regular flushing oil and filter change is important.

I would get the Turbo checked out same time as on this model it could well be a Turbo and engine change if its gone that far due to the metal particles contaminating the engine.

Yes, your intercooler is a problem cos it cools down the turbo charger. The turbo is what gives you your extra power, and when it overheats, it loses pressure and thatcauses loss of power.

Total loss of power steering on Ford EL futura.


The first thing to do is, isolate the problem. Crack the
the pressure line loose at the back of the power steering pump. If you can get at it, if not, jack it up put a stand under it and try to loosen it from the bottom.Or you can loosen the pressure line into the
rack.(or steering box as I don't know the year of the car) Snug up the line, and put on safty goggles.
Have somone get behind the wheel. Make sure the
ps fluid is full. Start the car and slowly loosen the line
a bit so the fluid shoots out have your helper turn
slightly to the right and back to center, then slightly
left and back to center. Each time the wheel is turned
the pressure should increase, if that happens, the
problem is in the rack.(or box) But if you have weak
pressure from the pump, the pump is bad.
Hope this helps. G,Day

Ford f250 2003 super duty diesel 6L - loss of power and idle fluctuates


icp sensor, definitly. you can get to it but you have to go from the bottom. remove the trans filler tube, and lower the the trans slightly, then you can remove the turbo heat shield and get to the sensor, you will need a 1 1/16" 12 point crows foot socket for the sensor its self.

Loss of power on hills


Hi, i think i answered you in another post.
If not then the likely cause of your problem is turbo related the most common cause is one of the pipes going to the turbo has a small split in it causing this problem.

Nearly all the diesel turbo cars with your problem usually means a pipe needs replacing for the turbo this will need to be checked as it can be difficult to find the damaged pipe because they work under high pressure so actually seeing the damaged part can be difficult so check properly.
If you are unsure then get a garage to check this as they will know the fault and will have a good idea exactly which pipe is damaged.
Worst case of this will be that the turbo needs replacing but this is in the most severe of cases the turbo can blow if the pipe has been damaged for to long as it will be working under the wrong pressure.
What happens is when you acelerate the turbo builds up pressure giving you more power when you need it but when the pipe becomes damaged this pressure is lossed and you then lose power and will cause black smoke coming out of exhaust.

Hope this is some help to you but if you have any problems or questions then give me a shout back and ill be glad to assist you further ok
